@meade -- Could you please look into the issue, kindly re-assign if this is not related to your changes.
Thank You.

Sounds like the browser got into a weird state if it was fixed by killing all chrome processes.

Rune, is this affected by your changes?

I doubt it. This is Chrome 55, and StyleResolver::appendAuthorStyleSheets and StyleResolver::appendCSSStyleSheet are gone on master, but I don't know if of my changes should fix or cause this issue.

Well let's just watch out for crashes including updateActiveStyleSheets in their stack traces from now then.
