Found while fuzzing mozilla-central rev 3059084abf6e (built with --enable-debug) with the pref `gfx.e10s.font-list.shared` enabled.  Firefox must be run using XVFB in order to trigger.  Further, I am only able to reproduce this issue on my local machine.  I've tried several other instances of Ubuntu 18 without luck.

I bisected this bug to the following build range:
https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=c8f201bd3c0c551f8735a4a6a8ed9bcd34052af2&tochange=2f8d4f1f660836c1c7b71a573dfe015694d30c86

It appears that this may be a regression from bug 1647573 or bug 1648355.

Assertion failure: faceMap, at /builds/worker/checkouts/gecko/gfx/thebes/SharedFontList.cpp:483
