DMN Editor: Command shortcuts affect the diagram when in Node Editor mode

Scenario 1: Make a DMN diagram. Open a Decision Node for example. If you press backspace outside of a text field the editor for the Node editor stays open, but the node has been removed from the diagram.
Scenario 2: Make a DMN diagram with nodes. Copy one node. Edit another and hit ctrl+v. The editor closes and view jumps to diagram view.
