I was TBR'ed without being included on the CL, see Issue 500032 for that...
All the failures look like they occurred with various CQ patches applied.

 Issue 823396  has been merged into this issue.

 Issue 823396  is also disabling BrowserTest.WindowOpenClose2, maybe we should proactively disable more fixtures or find a fix soon?
