The contextChange event is fired when: * Changes to insertion annotations * Changes to which nodes are selected (start/end nodes have changed) * Attributes have changed on any element (it's probably more expensive to detect if the changes are relevant than to just emit the event and let listeners do their thing) This fixes most of the strange behavior with the toolbar not updating properly.
