It is common to send a high number of this IPC message from the UI process to the WebContent processes during
brightness changes of the screen. To avoid sending this to suspended WebContent processes, and creating a
large IPC queue for those processes, we should coalesce the messages and send them when the WebContent
processes resumes again.
