--- Comment #5 from Kurt Revis <krevis at figma.com> ---
AFAICT the WKContentView's gesture recognizers are operating normally -- events are coming through.

Tried making the WKContentView stop watching applicationWillResignActive and applicationDidBecomeActive notifications, but that didn't seem to affect anything.

Only difference between good and bad states that I can find: Set a breakpoint on `WebPageProxy::didReceiveEvent` with a condition "($x1 & 0xFFFFFFFF) == 0". That catches the response from the content process after sending the event.  

In the good state, the second argument 'handled' aka $x2 is true. In the bad state, it's false.  So, something different is happening in the content process, but it's hard to tell what.
