[Ubuntu] Leaving Emacs moves point out of mini-frame

[zck]

From emacs -Q, evaluate the following code:

(require 'package)
(package-initialize)
(require 'mini-frame)
(mini-frame-mode t)

Then:

1. Type C-x b. A mini-frame opens prompting to switch to a new buffer. Point is in that frame.
2. Change focus away from Emacs, to any other window. Focus could be changed with Alt-tab or the mouse.
3. Change focus back to Emacs. Again, this could be done with Alt-tab or the mouse.
4. Note that focus is no longer in the mini-frame, but back in the original window point was in before we typed C-x b.

I'm running mini-frame from version 31380e7.
