Please update the telemetry descriptions so that it's clear from reading them that they are main-thread only.

Can you say MAIN_THREAD instead of MAIN? Our histogram names aren't notable for their brevity, and I think this will be easier to understand.

I can take a closer look if it still fails after that.

Needs work from bug 1342635 to uplift first. OK for beta.
