See the comment. A bit racy, but some of the time crashtest crashes
without the patch.

Null-check is just paranoia.

I been having tab crashes going to https://app.townsq.io/login?redirect=%2Fw%2F59fa42c059cb9712dbda7aa1%2Fhome and trying to print the page.

Bug 1671480 was closed as a dupe of this bug. I'm moving the Fission Milestone == M6c from that bug to this bug for Fission project tracking.

Backed out changeset 6d63e8bc04bf (bug 1671503) for Crashtest failures in layout/printing/crashtests/1671503.html. CLOSED TREE
