[Alexandru Michis [:malexandru]]

Hello Graham,
I believe this could be caused by the changes in Bug 1558851.

This seems to permafail on Tier 2:

[Andreea Pavel [:apavel]]

Based on retriggers it doesn't seem like this is perma failing, just has a high occurence when it's retriggered.

Retrigger range: https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&fromchange=8bce401b8833e8a2b4d187c507c075079275d8ca&searchStr=android%2C7.0%2Cx86%2Copt%2Cweb%2Cplatform%2Ctests%2Cwithout%2Ce10s%2Ctest-android-em-7.0-x86%2Fopt-web-platform-tests-1proc-6%2Cw-1proc%28wpt6%29&tochange=2901d32eddaa6accd04b30725c7307338e94f48f&selectedJob=252857529&group_state=expanded

Comment 6

[Edgar Chen [:edgar]]

See https://bugzilla.mozilla.org/show_bug.cgi?id=1550290#c8. This all happens on android platform, I suspect it is because the emulator is too slow to finish the test, maybe extend the timeout would help.

Comment 8

[Maja Frydrychowicz :impossibus (was :maja_zf) (needinfo me)]

This seems to happen on Fennec only, and wpt will be turned off on Fennec in Bug 1558334.

[Edgar Chen [:edgar]]

Close this as WONTFIX given that WPT is turned off on Fennec.
