@acondor -- Could you please look into the issue, kindly re-assign if this is not related to your changes.
Thank You.

Doesn't look like this was caused by Aldo's CL, which only affects Android.

Not sure what's going on. Assigning to thomasanderson@ for triage.

/cc+ thestig@, derat@ because fonts.

Seems like an internal issue.
