oom crashes with this pattern are showing up increasingly in firefox 60.

Need a prioritization here.

Many of the stacks on this crash bug probably belong in bug 1448868 where more investigation is happening. I don't see anything significant coming into the CSS Media Query code since Firefox 57 to have this spike now. That is, I don't think these are new OOMs. Marking this P3 for now, though will likely dupe it to bug 1448868.

Closing because no crashes reported for 12 weeks.
