Since the status are different for nightly and release, what's the status for beta?

Hi Mike: Is it possible to get someone to look at this eventually and set a priority?

Comment 8

[Augusto Pace]

Hi,

I was able to reproduce this issue on Ubuntu 18 with Firefox version Nightly 76.0a1 (2020-03-17) (64-bit). Marking that flag as affected.

[Mike de Boer [:mikedeboer]]

The regression window in comment 2 doesn't contain a commit that looks like an obvious culprit to me :(
So I think this'll need some old-fashioned debugging and fixing.

Priority is low though and there's no sign of dataloss. Not sure if this is worth tracking; I think not.
