It acts like you hit the close button, because I did have something open, and it asked if I wanted to save first.

It almost seems like that's what it's supposed to do, like a hidden feature.

Closing, this not a bug, it's a shortcut for closing the app. (I'd remove it if I could because this has been reported as a "bug" a lot, but AFAIK it's buried within our UI library.)
