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

Component: CSS Parsing and Computation → Graphics: WebRender

Seems like we can probably just fuzz this?

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.
