Log Message:
-----------
[Site Isolation] [macOS] UI Process may crash during gesture event handling
for cross-origin frames.
https://bugs.webkit.org/show_bug.cgi?id=302439
rdar://164432967
Reviewed by Wenson Hsieh.
Previously, a race condition could cause the UI process to crash when
processing gesture
events due to a mismatch between the type passed to
`WebPageProxy::didReceiveEvent` and
the event type of the first event in the gesture event queue. Resolve this
issue by
waiting for the web process to handle each gesture event before sending the
next one,
just like we do for mouse events.
