Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/9984945dbe893379b16d01093c5cd30801ff782e (Scrolling with Mac mouse don't cause rubber banding.). If this is incorrect, please remove the owner and apply the Test-Predator-Wrong-CLs label.

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.
