It's a bit early to fully guage the state of 65.0b2 [1] but early results with suggest this patch hasn't helped at all - the crash rate hasn't changed in either absolute terms nor relative to other crash signatures - still ~30% of crashes. So more investigation is needed, and I think it is premature to uplift even a correctness patch to ESR - in part because the crash signature doesn't even exist in 60.4.0.
