Created attachment 59475 [details] test case Text content generated by :before and :after selectors should not become part of any annotated ruby base. I.e., for <ruby>base<rt>text</rt></ruby>, "text" should annotate only/exatly "base", regardless whether there is additional :before or :after content. Added a test case.
Created attachment 60847 [details] patch - explicitly handle generated content
Created attachment 60998 [details] patch - explicitly handle generated content (skip on gtk & qt)
Addendum to patch: No Windows baseline for the new test yet. (Also, please note that I will be away for the next 2 weeks on vacation and can't respond immediately to reviews and queries.)
Created attachment 66477 [details] Patch
Uploaded a new patch that subsumes the fix from https://bugs.webkit.org/show_bug.cgi?id=43722. Since this changes the code that was added by that patch I think I should request a new review. Also, extended the layout test from 43722 to also test for floated ruby elements (making them block elements) and adding a similar test for :after content.
