Using the per-revision bisect providing the bisect results,

Good build: 55.0.2862.0 (419063)
Bad build: 55.0.2863.0 (419330)

You are probably looking for a change made after 419066 (known good), but no later than 419067 (first known bad).

This is weird.

The CL mentioned in #1 is already reverted by r420023, and can't be still effective in 55.0.2874.0.

Routing back to test team since the suspected patch is already reverted.

With response to comment #3: Re-bisected this issue on different machine and found the range below.
Narrow bisect:
https://chromium.googlesource.com/chromium/src/+log/cf6c1bd20618194c526ab0aa1f5780217523da5d..acf8c15189e568e8185b8c278cfa49e751dc1061?pretty=fuller&n=100

Suspecting: r419051 or r419071 ?

@dschuyler: Kindly help to reassign if your changes are not related to this issue.
