Set release status flags based on info from the regressing bug 1887810

:gw, since you are the author of the regressor, bug 1887810, could you take a look? Also, could you set the severity field?

Adding the same comment as https://bugzilla.mozilla.org/show_bug.cgi?id=1889844#c8
:gw could this be triaged?
The Fx126 soft code freeze starts this week, Fx126 goes to beta on 2024-04-15.
Should Bug 1887810 be backed out of central to give time to investigate? Bug 1888400 was already backed out.

I've asked for that patch to be backed out for now.
