Pressing `ESC` while entering a pulse closes the whole window without saving

When entering a pulse, if you hit ESC at any point, the whole pulse window closes, thus losing all progress. When I enter a pulse, I often look at Risk/Success Factor drop-downs. If I don't find what I'm looking for, typically hitting ESC in your browser only closes the drop-down pick list. If nothing else, Pulse entries should show the typical browser pop-up making you confirm that you will lose unsaved content by exiting, giving the ability to come back and save/cancel.
