Number scrubber seems to stop working for some iPad users #48

Scrubbing doesn’t update the canvas. Reloading the page resolves the issue.

I haven't been able to replicate this, it's super-frustrating! I definitely don't want this bug to go live, though. Oof!

It might be performance related. I know using the number scrubber is especially chunky on an iPad 3 (and the older devices seemed even slower in our testing).

I’m trying to reproduce it and it’s pretty sluggish for updating the canvas on this iPad 3, but I can’t quite get it to break like the kids broke it.

We no longer use a draggable number scrubber, as of this: https://github.com/Khan/live-editor/commit/8f3de60f25ec91f1d28446f135f5b8ff7a05e2ab
