Also happening with: CrossProcessMouseCapture

In both cases the hit test data for the expected_target has arrived in the browser process.

Also SitePerProcessHitTestBrowserTest.TouchpadPinchOverOOPIF*

Reproduced today ahead of triage

I expect to land a CL today that includes a rewrite of  SitePerProcessHitTestBrowserTest.CrossProcessMouseCapture, I don't know if it will help or not.

Since you are re-working this test, could you re-run them under Viz to ensure that the input events are being acked?

Thanks

SitePerProcessHitTestBrowserTest.CrossProcessMouseEnterAndLeaveTest /1 and /2 both still fail under Viz
SitePerProcessHitTestBrowserTest.CrossProcessMouseCapture           /1 and /2 both still fail under Viz

All time out in InputEventAckWaiter::Wait for the first call to RouteMouseEventAndWaitUntilDispatch. Meaning the events are not arriving at the expected target.

It looks like the rewrite did not resolve the issue. Could you take a look?

Update viz_content_browsertests filter.

Undo revert in https://crrev.com/c/1134144 which didn't end up being
needed. Revert was in response to FindIt and failures in
SitePerProcessBrowserTest.ViewBoundsInNestedFrameTest but that problem
had already been addressed.

These tests are failing for the same reason as SitePerProcessHitTestBrowserTest.RootConsumesScrollDuringOverscrollGesture, I have a CL that can fix both
