Testcase found while fuzzing mozilla-central rev 42593af5ec7ec9d5a07c9c0e899ac99244d15ae6.  Testcase bisects back further than a year which is as far back as taskcluster stores builds.

Probably a nscoord overflow somewhere due to "border:7108865mm solid".
I don't think anything bad can happen as a result, so it's low priority.
