Expectations marked in r292061

There is no chance r290898 is involved in this.

Thanks for taking a look! 
Today I will attempt to reproduce locally and bisect an exact point.
Comment 7 Dawn Morningstar 2022-04-21 14:58:02 PDT
Unable to bisect as when attempting newer spades I receive ('Failed to install app {} on device {}'.format(self._path_to_driver(), device.udid)) 

At r291781 the test passes at 1000 iterations using run-webkit-tests --ios-simulator
