Looks like chrome crashed. So this might be chrome regression.

In that case it might be fixed by https://chromium.googlesource.com/chromium/src/+/cd46b1e9ac4ea2d8f8492022dcb3638ef452f038

I'm giving this the benefit of doubt: I stopped landing of https://codereview.chromium.org/2184703002/, assuming that the recent commit cited in #2 would remove the flakes. If they return, I might resume landing that CL and will reopen this bug.

The culprit in chrome was reverted in https://codereview.chromium.org/2175313005

The test is not disabled.

Thanks for update vabr@. I should refresh window before posting :)
