This will debounce the notification at 16ms granularity, which seems too low for something that's loading over the network. Maybe use a Timer that debounces on the order of 100s of ms? We also have the AlarmClock with "snooze" feature for this sort of thing.

Gallery loads 6 fonts, they are coming in within 1ms of each other. 1 font sometimes misses 16ms window and markrelayout is called second time. 100ms would delay app first build for many frames, there is no easy signal to cancel the wait and complete future.
