Using the per-revision bisect providing the bisect results,
Good build:57.0.2986.0 (revision : 444600)
Bad build: 57.0.2987.0 (revision : 444943)

You are probably looking for a change made after 444928 (known good), but no later than 444929 (first known bad).

CHANGELOG URL:

The script might not always return single CL as suspect as some perf builds might get missing due to failure.

From the CL above, assigning the issue to the concern owner

A friendly reminder that M57 Stable is launch is coming soon! Your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and get it merged into the release branch ASAP so it gets enough baking time in Beta (before Stable promotion). Thank you!

Gentle ping..!
einbinder@: Could you please take a look into this and help fixing it as this is marked as Stable blocker and the M57 stable push is nearing.

A friendly reminder that M57 Stable is launch is coming VERY soon! Your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and get it merged into the release branch (2987) ASAP so it gets enough baking time in Beta (before Stable promotion). Thank you!

URGENT - PTAL ASAP.

We're getting VERY close to M57 Stable promotion. And 
this issue is marked as M57 stable release blocker. Pls make sure to land the fix and get it merged into the release branch ASAP so it gets enough baking time in Beta (before Stable promotion).

Know that this issue shouldn't block the release?  Remove the ReleaseBlock-Stable label or move to M58.

Thank you.
