From the crash stacks, ImageBridgeChild::SendWillClose() sent correctly, but somehow it does not received a result of the sync ipc message.

With the following search, crash on ImageBridgeChild::SendWillClose() seems not a new problem.

Last crash with this signature was on the July 16th build.

The small spike on 7-17 went away. I think we can probably close this was WFM if everyone agrees.
