(1), (2), and (3) are fixed. We didn’t directly fix (6), but we haven’t seen it in a while

Thanks so much @heyimShivam, this is really helpful! I took a quick look.

For 5), isn’t that a “Unhandled promise rejection: RequestError: read ECONNRESET” flake? In general always look at the first thing that occurs – if an earlier test fails then later ones may fail with stuff like “Login page did not load” but that is not the “real” flake.

The one that we haven’t seen before is 1). It seems related to setContent() so maybe it’s a residual flake after the recent fix in #15806. Thanks for raising it – I’ll bring it up with Chris tomorrow.
