Mount Events can inform you about certain stages of the Node's lifecycle,
letting you perform the required initialization / cleanup.
They are also used internally for managing the lifecycle of stream subscriptions.
A Node is considered mounted if it's present in the DOM, i.e. it has dom.document
among its ancestors. A node that is not mounted is considered unmounted.
All MountEvent-s are cascading: if a certain event is fired on a node, it will also
fire on all descendants of that node.
