The layout test timeouts are 260ms because the fake mousemove events are sent on 250ms timers. (Urgh.)

Can you use a busy wait here instead of a 0.5s wait?

That'd be a bit weird, since I'm waiting for something *not* to happen.

I'm gonna land this as-is, if it turns out troublesome, and you're reading this comment in the future wondering what I was thinking, sorry :|
