Fun: the transition is handled at two different places, once for dom
nodes, once for components. Obviously, I only applied the change to the
first case and forgot about the second.
In this commit, we uses the "!" as suffix to designate an event that
should be captured. This is inspired by the Vue source code.
This solves the issue of communicating additional information to the
underlying virtual dom. However, this will most likely disappear when
we rewrite the vdom as a virtual block system.
