[Emilio Cobos Álvarez [:emilio]]

This is the same underlying issue that bug 1766082 fixes, I believe, so once that's fixed it's a one-liner to address this.

This moved to tier1: https://treeherder.mozilla.org/logviewer?job_id=376467915&repo=autoland&lineNumber=6895 but seems intermittent

David, do you know if you're going to be able to address the comments in bug 1766082 soon-ish? Happy to do it myself otherwise if you are busy :)
