I was moving the tests for bug 302186 into the new test layout, and four of them have regressed since december or so. In the attached test case, the last two have always failed and were marked todo(). the four other failures are recent regressions.

I get a regression range between 2007-02-08 and 2007-02-09: http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=all&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2007-02-08+04&maxdate=2007-02-09+09&cvsroot=%2Fcvsroot My guess is a regression from bug 348809.

bz mentioned a while ago that several tests would regress when he landed the patch for bug 348809. I think it's this change: - document->ContentStatesChanged(oldElement, newElement, + document->ContentStatesChanged(newElement, nsnull, NS_EVENT_STATE_DEFAULT); We were notifying on an element when we shouldn't have, but because we did we passed those tests. bz will of course know way better than I do!

Yeah, that's exactly it. See bug 302186 comment 43. We could put the notification back for now, I suppose, but I'd rather leave the tests as todo() and fix bug 229915 (which will automagically fix these tests, as well as all sorts of other things).

Fixed by checkin of bug 401291, which fixed bug 229915, at 2008-02-18 22:17 -0800.
