[GTK][WPE][Coordinated Graphics] wheel event async scrolling doesn't work while the main thread is blocked 1. Load the content 2. Send wheel events to scroll 3. Sometimes, the page doesn't start scrolling promptly This content repeats blocking the main thread for 2 seconds, and waiting for 1 second. If the wheel event is dispatched while the main thread is blocked, the async scrolling doesn't start until the block ends.
