Marked Test as Flaky in r251314

[Alexey Proskuryakov]

The suspected revision is very close to r251261, which caused other failures. Seems worth verifying with a local repro.

We are actually rolling it out due to the associated bug, but this may not be the regression point.

[Alexey Proskuryakov]

This test is still flaking after the rollback.

[Simon Fraser (smfr)]

Seems like it's a rare flake on WK1 only.

[Alexey Proskuryakov]

It still is the case tha this regressed a week ago.

This hasn't been flaky since r251565 when a related r251261 regression/bug was fixed. I was also able to run it locally against r252065 a total of 1,100 times with no failures. Patch posted to remove the flaky test expectation.
