Support `word-break: break-word` please.

Object-fit and object-position is defined for all visual media, not only for images, but also for video or canvas elements.

As outlined in the linked issue, having the ability to use grid-gap on flexbox (which is soon to be renamed just "gap" by the CSS Working Group because "grid-gap" doesn't make sense when used on flexbox) solves a major pain point that developers are facing.

See the issue for more details:

even when `list-style` is set to `none` for lists MS Edge stil rendering the list bullets. Looks like `list-style: none` is completely ignored by MS Edge

Used to declaratively create a new stacking context.

Make the use native font stacks (https://css-tricks.com/snippets/css/system-font-stack/) easier to use by implementing the system-ui (https://www.w3.org/TR/css-fonts-4/#system-ui-def) property.

unsupported pseudo class renders CSS useless
When MS Edge does not support a pseudo class (e.g. :focus-within), it ignores other grouped selectors such as:

#menu:focus-within, /* remove this to make it work in Edge */
button[aria-expanded="true"] ~ #menu {
-webkit-transform: translateX(0);
transform: translateX(0);
}

Is this the correct behavior?

CSS Media Quries Level 4 bring in a bunch of syntactic improvements. They make media queries much more readable and maintainable.

https://drafts.csswg.org/mediaqueries-4/#mq-syntax

Here's an example:

Before:

@media (min-width: 20em), not all and (min-height: 40em) {
@media not all and (pointer: none) {
…
}
}

After:

@media ((width >= 20em) or (height < 40em)) and (pointer) {
…
}

Mozilla Firefox and Google Chrome have a native eyedropper to capture screen colors just by "clicking on them." The result can be chosen as "RGB", "RGBA" or a simple color code. I have not found any similar solution for Edge even in extensions and I really need this feature.

Firefox Nightly now supports paint-order for HTML text:

Idea you have my utmost diversion.

We need outside strokes for text, because the current centered strokes are not pretty - the intrude the font fill.

An image illustrating how centered strokes aren't pretty / don't do what typically is intended (leaving the fill of the font unaffected):

I hope you will implement stroke-align:outset.

The Internationalization WG observes that Edge does not pass the tests found here:

See https://www.w3.org/International/tests/repo/results/counter-styles.en.html (click on the large text in the left-most column to run the tests)

Several groups have observed the need for counter style support. The Arabic Layout TF finds that it is needed for Persian support. Richard Ishida reports that vertical text lists require it as well. Firefox is observed to provide this support.
