Creating this bug so we can link known issues around the problem. See https://bugzilla.mozilla.org/show_bug.cgi?id=1248444#c3 and following for a gist of the problem.

Unsure if we want to do this, or the extent to which the web depends upon it. But Blink/WebKit/Edge allow it.
* Bug 1248444 relied on document.styleSheets[0].insertRule(s, 0) working.

* web-bugs#2990 relies on document.styleSheets[i].cssRules[i]selectorText.replace(':hover', ':active') working.
