J.C. is this from bug 1551230? appeared on this merge: https://hg.mozilla.org/mozilla-central/pushloghtml?changeset=3c7f3988e7045742252732b4948b6fa851ff6057

Ah, ok, we're going to have to disable the Android-enablement pref for the mochitests.

Patch for this in Bug 1551342. I'll be duping this on that when it resolves.

I'm pretty sure this is fixed in Bug 1551342.

Thanks for reopening. I'll have to dig into this WPT failure next week. Keeping this assigned to me.

There are 31 total failures in the last 7 days: https://treeherder.mozilla.org/intermittent-failures.html#/bugdetails?startday=2019-05-26&endday=2019-06-02&tree=trunk&bug=1551382

Recent failure log: https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=249577241&repo=mozilla-central&lineNumber=5511

The solution here will be disabling this test on Android.

Actually, correction, this can be fixed with a pref fix. Attempting on try.
