html image map stops working on iOS Safari

So, there's an html page with an image map (img tag with usemap attribute) and clickable areas. Lately, I think after iOS 15 upgrade on iphone (XR, XS, 13), Safari stops firing onclick event on areas. Initially onclick works if you tap lightly, with quick finger presses, but as soon as you tap a little longer (just a bit stronger tap, or a long press) it starts behaving as if there's no map and areas associated with the image.
You can test here https://demo.rezmagic.com/maptest.html
If you see "area click" messages, it works correctly. When you start seeing "image click" messages, it means it's broken - it does not detect areas anymore. If you reload page, it starts to work correctly again.
Any ideas on what's going on here? Possible workaround? I submitted a Safari bug on Apple feedback but I am not sure it was the right place.

meeks seems to be correct about the OCR capability of newer Safari browsers breaking image maps.
The following is one workaround that you can use, but it will break the OCR capability:
Create a transparent gif of the same size as the imagemap. Let's call it placeholder.gif. Then add it in-front of the actual image and put an image map on that, like so:
<img src="placeholder.gif" style="position: absolute; z-index: 10;" usemap="#Map" />original image here
It works for me.

This is absolutely a Safari bug on mobile and desktop and it's been driving me nuts. Your image doesn't replicate the issue on desktop safari, but those with higher resolution and more obvious text do.
What's happening is that Safari now OCRs images to allow users to select and copy text from them. It does this by adding shadow DOM elements containing the text that float above the image, all contained within one DIV that entirely covers the image. This doesn't happen instantly, but seems to take a little time and perhaps depend on user interaction with the image.
You can watch this happen by opening the MDN web docs page for the map element here and looking at the Example (not the demo) with Inspect Element. The img tag with the map starts out simple, but once it shows that it has children you can expand it and see the shadow DOM elements. Once those are added the map no longer functions, presumably because the overlay elements pass through clicks to the image but not the map.

I had developed a workaround where you listen for click events on the image, get the click event's offsetX and offsetY coordinates, then iterate through the elements to compare the event's offsets with the coordinates, and then trigger a click on the that matches.
However, then I realized that iOS 15.4 came out today and so I upgraded my iPhone and it seems to be fixed now without any workarounds. So just upgrade and you should be fine.

Jquery touch punch works for Chrome and Firefox but not IE

I am using the jquery touch punch library to enable users to move images around via touch. This works fine in Chrome and Firefox but will not work in IE.
I find if I hold down on the image in IE a small square appears and I am able to drag the image within the boundaries of this square but no further. I guess this is the right click function kicking in.
I have looked around and most people are saying to add '-ms-touch-action: none' to the css of the draggable div. So I added that to the style attribute of the draggable div and it did nothing. I am still unable to drag in IE.
I've looked around for another alternative but am unable to find one. I have included jquery 1.8.1, jquery ui 1.8.23 and touch punch 0.2.2. Any help will be greatly appreciated.

I noticed the htm page I was launching containing the draggable div contained a meta tag which was emulating the page in IE9. 2 and a half days I spent on that! -ms-touch-action:none will definitely work in IE.
If you have come here and are experiencing the same issue but the above paragraph didnt fix it for you, try this:
In IE click the cog and go to Compatabilty View Settings and uncheck the box for Display intranet sites in Compatability View.

Is their any responsive lightbox with slideshow that has proper swipe?

I have been search for hours for a jquery type plugin that is responsive and also has proper swipe animation during gesture.
http://www.photoswipe.com/ is 99% there except that it dosent support single image lightbox mode, its geared towards grouping images into swipable galleries, which it does brilliantly.
However now and then I may want a few images on a page to have no relation to each other. Id rather have a default class, that when used all images opened up in a single image lightbox. Photoswipe automatically groups any images given the same class.
If I was able to set an option with this plugin to hide the prev/next images on a call, then it would have been perfect.
Important though, is that the plugin must use full screen like photoswipe does. So many responsive plugins seem to waiste the screen with unrequired image chrome. The intended slide show or light box should be like viewing a gallery on a smartphone - again photoswipe does this. its only fall back in being able to have non related instances.

There are a couple out there that appear to be inline with what you want. I never understood why some developers create "responsive" galleries, but waste so much space with padding or decretive chrome elements.
I was thinking of using PhotoSwipe, but the developers stopped supporting it and recently threw it out there for the open source community to maintain. Kind of turned me off during the transition.
Here are a few others I came across that I'm considering myself.

Rendering bug in Google Chrome at certain window widths

My users and I are running into a rendering glitch in Chrome only (on both Windows and Mac) where an overlaid div that I'm using for on-hover tooltip-style "popouts"(see first image below) does not get rendered properly in certain cases (see second image below). In all other browsers I've tested, it works as expected.
Here's how the hover popouts are supposed to look (and what happens in Firefox, Safari, IE):
Here's what happens in Chrome:
You can see it in action on this site if you look at May 24 using a browser window width of ~ 1200px (significnatly wider or narrower windows do not seem to work). The glitch only affects the popouts in the bottom right of the menu that are popping left, e.g. those on May 24. Hovers using the same exact mechanism higher up in the page work just fine. Glitched popouts are invisible (except for part of the carat), but if you click on the link to lock the popout in place and then hold left click while moving your mouse around as if to "select text" in the area where the popout should be, it will then render partially. Also if I open dev tools and try to select the popout, it will render just fine at that point.
I've been looking at this all day and trying different work arounds with opacity, z-index, etc. and getting nowhere. Does this glitch ring any bells for anyone? Is there a way to force Chrome to render the div, once its been positioned and unhidden? I'm fine with any work-around or hack.
I use a custom (and fairly complicated) jquery plugin for popouts. If it would be helpful to see the non-minified javascript for the plugin, I can post or provide a link to that, but general guidance that leads me to a work around will be sufficient to be accepted as an answer.
Edit: My Browser Build: 26.0.1410.65

(Per my comments)
This does indeed seem to be a bug in Chrome, though without a smaller test case to reproduce it, it could be very hard to track down. You may want to report it to the Chrome team with as much information as possible.
In support of my "it's a bug" assertion:
The hidden/clipped elements become visible when they are selected.
The elements underneath the hidden/clipped elements are not clickable.
This indicates that z-index and height is correct.
It only happens under very specific circumstances; the rest of the items with the same style work fine. The same item may work fine at a slightly bigger/smaller screen width.
Applying a 3D transform fixes it.
The problem goes away when I apply a CSS transform such as scale3d or translate3d. I imagine this is because certain CSS properties cause the browser to switch to GPU acceleration.
In this case, switching to the fast path for rendering seems to alter the drawing sequence enough to fix the problem.

Super hacky but this fixes it for me:
$('.drop-link.food').on('hover',function() {
$('.tool-tip').css('overflow', 'hidden').height();
$('.tool-tip').css('overflow', 'auto');
});
Obviously this isn't a "good" solution, and even remaining hacky you could probably optimize it to only force the redraw on the tooltip it needs to, but hopefully it helps...
Another clue:
$('.drop-link').on('hover',function() {
$(this).siblings('.tool-tip').css('display','block');
});
This won't fix it right away, but it seems like if this is there, once you've hovered on something, it will work the next time you hover on it.

Not sure if this helps with your situation, but over the last couple of days I've started to notice that certain site elements on Facebook and Weight Watchers no longer show up. Specifically it seems to be affecting items that (I believe) to be controlled by or dependent on Javascript. When I call up these sites in Firefox and Safari they work as expected.

Sliding panel for mobile page

I have a div which is mostly off page but uses translation on hover to display on the main page.
This is my site.
However, on mobile devices this isn't the best solution to display this div. Hover doesn't work well and I have to click often to get it to show up. I'm wondering if it's possible to do it like mobile applications where if I move the page to the right edge enough, this content will display or with a button. Something like this:
Any thoughts on if this is possible or how'd id solve this?

This pattern is called 'Off Canvas layout'. Documented (with some CSS) at http://jasonweaver.name/lab/offcanvas/
There are multiple implementations you could have a look at, perhaps start with this nice demo from Zurb: http://www.zurb.com/playground/off-canvas-layouts
As regards the use of hover, you're better off using a tap/click on both desktop and mobile for consistency. The 3-bar menu button is fairly universally understood these days.
