Why is this? "Transition events" more accurately reflects enter/leave/over/out
behaviour because these events can fire even w/o the pointer crossing the
boundary.

We can get rid of the "Node" from "NodeTransitionEvent" though.

I was trying to follow Rick's recent email to the pewg. It seems that there is
already a meaning for transition events.
https://drafts.csswg.org/css-transitions/#transition-events

Having this in mind, do you want me to keep it as transition events?

Missed the github comment, sorry. Your renaming looks good then.
