[csswg-drafts] [css-masking] Impact of masks on hit-testing needs to be specified (#11339)

smfr has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-masking] Impact of masks on hit-testing needs to be specified ==
Currently, [CSS Masking](https://drafts.fxtf.org/css-masking/#the-mask) says nothing about whether masks impact hit-testing (i.e. if clicks on the masked-out part of the content are treated as a click on the element).

Chrome and Firefox do consult the mask for hit-testing; WebKit does not. Test:

This was [reported as a bug](https://bugs.webkit.org/show_bug.cgi?id=284227) in WebKit.

CSS has historically shied away from specifying hit-testing, but I think this one is important. Also of note is that the spec does talk about the [impact of clip-path on hit-testing](https://drafts.fxtf.org/css-masking/#clipping-paths).
