bug#13953: 24.3.50; [Regression] The original size of the Emacs frame is restored automatically

[Dani Moncayo]

Recipe from "emacs -Q":
1. Resize the Emacs frame (and optionally move it).
2. Give the focus to another application.
3. Give the focus back to the Emacs frame.

When I do this, my Emacs frame is resized to its original size and its
upper-left corner is placed at the upper-left corner of the screen.

I see this problem in [1], but not in [2].
