This is pretty high frequency, considering this test mostly runs on try and mozilla-central.

Comment 5

[Jeff Muizelaar [:jrmuizel]]

Seems like we can probably just fuzz this?

Comment 6

[Kartikaya Gupta (email:[e-mail])]

WPT doesn't allow fuzzing so we'd have to disable it (since it's intermittent). But the test was added by cset 28777e333271 in that range. So it's not a regression on the WR side per se, seems like just a new flaky test.
