Doesn't repro. +perezju in case he wants to reopen/bisect more.

I don't want to ... :(

But the regressions are big-ish. It also seems something weird happened with the ref build at the same time.

Will keep this in my queue but with a low Pri.
perezju: is this still in your queue or do you want to close it?
Status: WontFix (was: Assigned)
Metrics did eventually recover so let's close now.
