Re-running the bisect, it seems to have repro-ed the regression but died.

Removing myself.
I moved some tests in "Replace NavigationURLLoader unittest [1/n]". It has nothing to do with performance. Probably a false positive?

Remove myself as owner for the following two reasons:

1) My CL only affects Android, this regression is Windows
2) My CL was already reverted

After a quick look at the seven listed CLs, I couldn't see an apparent culprit. Please re-triage this.
