that's why it's separate CLs. :)

I'll also send a note to chromium-dev@ if the base_unittests one sticks.

Ok, so I rebased to be sure and ran:
git cl try -b linux_rel:browser_tests -b mac_rel:browser_tests -b
win_rel:browser_tests
git cl try -b linux_rel:browser_tests_swarm -b mac_rel:browser_tests_swarm -b
win_rel:browser_tests_swarm

to ensure that every condition affected by this CL are covered and all the try
jobs went back green. As such, marking as NOTRY=true and enqueuing on CQ.
