https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=browser_tests&tests=WebRtcBrowserTest.RunsAudioVideoWebRTCCallInTwoTabsGetStatsPromise

Often time the test passes on the retry, but pretty frequently WebRtcBrowserTest.RunsAudioVideoWebRTCCallInTwoTabsGetStatsPromise generates leaks on the Linux LSAN/ASAN bot (including ChromeOS). The output is ginormous, so I'm only going to paste a portion of it:

Maybe the renderer is leaking a frame, or something similarly large during shutdown?

I'm not sure who should investigate this. I'm going to start with the owner of the test, they can hand off as necessary.

I'm also going to disable for the sanitizer builds on linux to cut down on the noise.
