Are this fx.hover and fullLayout._hoversubplot = subplot still necessary then?

Oops! Good catch. I change this back and forth and accidentally left both. Fixed in the commit below.

Oops. Yeah, you're right. There's still an extra item or two there. Fixing (and looking at the full diff when doing so this time)

Inset plots seem like a not-so-tiny corner case. But does this actually cause problems? Presumably mouseout happens before mouseover in that case?

Yes, which happens first was the question. If mouseover and then mouseout, it would end up unset, but the only time that could happen is if you move exactly one pixel outside of the inset region, which is where it started to seem like a small corner case. The second pixel moved will immediately fix things.

This wrapper isn't necessary, as all the items get gd passed as an arg.

Ahh, thanks. Wondered about that but assumed the opposite.
