Weird, just this single page on this single device. Traces show java_heap allocated objects in the browser process going way up. I'll kick a bisect with no story filter on a wider range.

=== BISECT JOB RESULTS ===
Bisect was unable to run to completion

Please try rerunning the bisect.


If failures persist contact the team (see below) and report the error.
