Description Chris Dumez 2019-03-06 15:03:33 PST 
ProcessDidResume() IPC should be sent upon resuming when ProcessWillSuspendImminently() IPC was sent. Currently, we only send ProcessDidResume() to the WebProcess if PrepareToSuspend() was sent, not when the more urgent ProcessWillSuspendImminently() IPC was sent.

This mismatch has lead to bugs because the WebProcess does not know it got resumed and failed to unfreeze the layers it froze upon suspension.
