I reproduced the crash, here is the main reason:
synthetic_gesture_target_base.cc(77)] Check failed: event.GetType() != WebInputEvent::kMouseDown || PointIsWithinContents(web_mouse.PositionInWidget().x, web_mouse.PositionInWidget().y). Mouse pointer is not within content bounds on MouseDown

The suspected cl (https://chromium-review.googlesource.com/779659) is not related to the crash and I could reproduce the crash after reverting the cl as well.

We need to change the gpu benchmarking not to crash in these scenarios of bad input.
