Developer Curb Appeal: Cloud Admin UI: no way back to Cloud screen after clicking node

When you view the graphical tree of nodes and click on one of them, you're taken to that other machine's main config page.

But you can't use the browser's back button to return.

Safari, Firefox and Chrome back button pops pup a dialog box and gives the error:
"404 Not Found get"

On all 3 browsers if you then click the OK button to dismiss the dialog, and then try the back button again, it works.
