It's not perma failing and the failure rate seems to be low. So I'm not going to disable the test.

Actually the failure happens more often as this try build shows. I'm going to mark it as pass/fail:
https://treeherder.mozilla.org/jobs?repo=try&revision=0432cbdfebea700328cfec73bf322f943d31c696

It looks like that this is not a failure anymore and now unexpectedly passes. As such I'm going to re-enable this test for Android over on bug 1847578.
