An expected user pattern with the new API is to request redraw after every EventsCleared.

On web, the event handlers are run instantly as events come in, which means there can be many more EventsCleared than the user expects.

I can think of two ways to address this:

• Don't run the event handlers as often, and buffer up events with a minimum time between processing them. This adds latency where it isn't necessarily needed, so it may not be ideal.
• Only run RedrawRequested events on a timer determined by the browser requestAnimationFrame API, which does slightly break the API contract.

I'm not sure which of these mitigations is better, so I would welcome discussion.
