That seems better. You still need to define how all the members are initialized.

You've only done this for a couple of events, while all the events
need to be dispatched as queued tasks from some kind of operating
system UI loop.

Yeah that seems slightly better.


What I'm missing still is that some of these events have actions
associated with them if the event is not canceled. So you fire the
event, you check if it's canceled flag is set, and then you run a
certain set of steps. That is not concretely defined at the moment.


Nit: "boundaries of all of its children", you want descendants there.


I'm a bit concerned too by the language of y is fired after x if z.
Can we not make that a concrete set of steps around firing x? It's not
clear e.g. if those are fired on the same task or on different tasks
at the moment. Or in other words, the modeling is somewhat sketchy.
