If that's too many events, couldn't the browser optimize by not spellchecking words until they scroll into view? I imagine that might not be terribly simple, depending on how the browser is designed, but maybe tens of thousands of events aren't too expensive anyway. I don't know, up to implementers whether it's doable. I'm assuming here that there's effectively no cost if no one's registered a spellcheck handler, so it won't penalize authors who don't use the feature.
