It appears to not be running tasks enough to get
MouseEventManager::FakeMouseMoveEventTimerFired to fire.
In addition, this failure is sometimes leaking into other tests and
making them fail.
It in particular caused a very hard to diagnose, flaky issue with
SitePerProcessBrowserTest.ChildFrameCrashMetrics_ScrolledIntoView
where sometimes the fake mouse event happened during that test by
mistake and caused an error (which was a real bug elsewhere in the
code, but still tests should not depend on each other.

Hmm. Now I can't seem to get it to trigger the fake mouse event. The test is still timing out though. Why does this test time out? It doesn't seem to be failing on the bots.
