(In reply to Hiroyuki Ikezoe (:hiro) from comment #0) > This is a regression very recently. I think I was wrong. This is not a recent one. I can reproduce this assertion with a revision two weeks ago[1]. [1] https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=15e32469eb048957223bac458140776a30251c6b

Priority P2 and block stylo-nightly meta bug because we should fix potential stability issues before enabling Stylo on Nightly.

I can't reproduce this anymore, both on tip and on my bug 1373018 branch (which cleans up a lot of this code)

Oh, I noticed an important thing that this assertion does hit only on *non* E10S.

The fix here is probably replacing the two GetParent()s in nsListControlFrame::AboutToDropDown with GetParentAllowServo()

Parent is only a good name the first iteration of the loop :P
