MouseLatencyBrowserTest.MouseDownAndUpRecordedWithoutSwap is flaky on Windows

Project Member Reported by clamy@chromium.org, Jan 9 2018

Issue description

The test MouseLatencyBrowserTest.MouseDownAndUpRecordedWithoutSwap is failing flakily on Windows bots with the following log error:

[ RUN      ] MouseLatencyBrowserTest.MouseDownAndUpRecordedWithoutSwap

 - element #3 is equal to "InputLatency::MouseUp"

(see https://uberchromegw.corp.google.com/i/chromium.win/builders/Win7%20Tests%20%281%29/builds/75545).

I'm disabling the test for Windows.

Hmph, the flakiness dashboard is crashing Chrome on all machines I've tried (https://test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=MouseLatencyBrowserTest.MouseDownAndUpRecordedWithoutSwap).

Am I just using the flakiness dashboard incorrectly?
clamy@ - any thoughts on how to best view flakiness data for this test?

It's also crashing for me, which is weird since it worked well yesterday. I've included one of the builds that was failing in the bug description. There were other failures that were similar.
Yeah, I'm hoping to be able to see whether it's been flaky forever, or if something caused it to become flaky.

This is flaking fairly frequently on Linux too in the bots.

cc'ing some folks involved in the recent work related to async targeting, in case this is related to that.

Dave, can someone from the input team take this on?
