I can also reproduce this.
After attempting to select any text/content with the mouse (or press ctrl+a), there is no selection highlight.
But selection API seems have valid range and pressing Ctrl+V also copy the content into clipboard.
So it looks like selection works but something is causing the selection highlight to stop working.

Attached file simple testcase —

Hmm the problem here is the style ::selection { background-color: revert; }. Probably Chrome is right that this should use the default selection background color.
Emilio, could you take a look at this (or pass it to someone else)? :)

Well... background-color: revert is basically background-color: transparent if there are no other rules, right?

Jan has been the one looking at highlight painting recently. Bug 2029839 is related, if we removed this chunk then this would be fixed... Jan, any strong opinions either way?

Worth trying it out, I r+’d the patch.

This works now.
