It looks like it should work.
Some things to consider:
1. Do you want the tooltip class to be swappable? i.e. what about warm-up and
warm-down? Posiiton bahavior? etc.
2. Do you need/want the measuring to happen on every roll-over? It’s a pretty
expensive operation. My implementation only measures once. That’s good from a
performance perspective, but bad if the sizes might change.
I’m not sure if there’s a “right” or “wrong” here, but these are some of the
considerations I’d make when creating a general purpose bead.
