Sorry, I wanted to add two important constraints here, but forgot to when I submitted the bug: this is for build id 20201229095620 (i.e. a Nightly build) in the last week of 2020. I also don't think this will be true for the general Beta/Release population.

> Anyway, did you find this by checking the new telemetry ?

Yes, based on https://sql.telemetry.mozilla.org/queries/77015/source (not sure if the query is stable).

If I interpret that correctly, there were a total of 3,927 failures, and 1,919 were due to this situation.

Definitely. Thanks for the pointer. I'll give that a look.
