depends really...
I guess that in most cases B should react.
A::dispatch [neston] -> B::dispatch [neston] ->
C::dispatch [unhandled] <- B::dispatch [handled]

We need to traverse down through dispatch functions until we reach the
inset that received the click. if not handle we back-track until we
find one that does.
This means in the cased of nested insets, it is the outer of these
that first reveives the click and this insets dispatch must realize
that it has a nested inset at the same coord.

What do you mean by merge here? If the only change is that you get one
huge function that better leave them as two distinct functions.
