rmargold@chromium.org and wfh@ apologize for another bug given we have bugs for the respective crashes and they are marked as no stable blockers but those bugs show that we are causing overall spikes and want to confirm one lasttime before we go M57 prestable next week.


Note : I haven't included any longstanding issues as part of the comparision, Also I picked 1 week old M57(57.0.2987.74) for comparison since the latest version of Beta is too early to compare.
