telemetry.internal.actions.scroll_unittest.ScrollActionTest.testWheelScrollDistanceWhileZoomed flaky

Project Member Reported by joedow@chromium.org, Jan 24 2018

Issue description

I've seen this test fail several times during my sheriff rotation.  Here is a link to one of the failures:

This is still flaking. I will disable the test.

I think you need to disable this on linux, not chromeos?

@bokan@ can you PTAL as this disable reduces automated test coverage?

I'll take a look when I can find some time to dedicate to this (and other failing/flaky telemetry tests). Unfortunately, that's unlikely in the near term. FWIW, I added this test recently since we had no coverage at all so we're basically at status quo :(
