:whimboo, since you are the author of the regressor, bug 1522790, could you take a look?

Please note that the referenced push is a backout of my patch from bug 1522790, which actually fixed this intermittent failure. Due to the backout the failure returned and will be fixed again when the revisions on bug 1522790 land hopefully soon.

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Let me actually pull off the fix from bug 1522790 and land it earlier to avoid keeping it in the list of revisions to rebase before we can finally fix bug 1522790.

There is also /css/css-scoping/font-face-004.html which needs to be fixed. Lets reflect that in the bug's summary.

Failed to create upstream wpt PR due to merge conflicts. This requires fixup from a wpt sync admin.
