Description Ben Nham 2024-02-28 10:32:37 PST 
Currently, every time a tab is created or destroyed, we update the hidden page timer throttling interval and broadcast the change to all processes, including suspended processes. While this doesn't cause a suspended process to resume, it can cause messages to build up in IPC queues that never get drained. This is because the receiver might be a suspended WebContent process. To avoid this, skip sending the throttling updates to suspended processes and update the timer at resume time.
