26.1%-753.2% regression in xr.browsing.wpr.static at 561578:566089

Project Member Reported by bsheedy@google.com, Jun 14 2018 
Bisect points to https://chromium-review.googlesource.com/1093423, but that doesn't really make sense. The story I used to bisect (the Google one) has extremely consistent results, but a couple of the other ones (Yandex and Youtube) have had this metric fluctuate a bit recently.

Based on that, I think this is a Won't Fix, as it looks like it's just some noise we get occasionally in benchmarks.

It is a pretty significant regression and it's not going down. I'm inclined to up the bugs priority and investigate further. WDYT?

If devs have spare time after the current push for standalone fixes, then sure. Note that the amount the metrics increased is very similar to  Issue 835456 , which is the last significant jump on the graphs.
