Splash Screen Occasionally Takes Far Longer to Clear #633

Based on my testing, every so often cwtch will launch and be stuck on the splash screen for far longer than normal - up to a minute.

My guess is there is some subtle asynchrony issue which every so often forces the splash screen to wait a long time for the clear message - perhaps an event bus flood?

This has little impact except annoyance and the occasional failed pipeline test (because splash screen dismissal times out at 10 seconds)
