@jelly The c9s failure here in testBookmark is the same failure as in your 2-2 downstream update. There it also failed testKeyboardNav, which passed here. But it at least reproduces half of the problem on the upstream side. It failed the same way in #624, so it's either a race that isn't too hard to reproduce, or it actually reliably broke just a few days ago.
