Yes, this particular case has been fixed, thank you. 

I recall the general case being discussed but not addressed (closing windows which have popped open just for a specific buffer), but I'll file a separate report when I observe a striking example.

I reproduce this with a current build, with emacs -nw -Q.

When reverting to revision e78283bb (Tue Aug 18, just before minibuffer-hide-completions was introduced), the problem goes away and the *Completions* buffer continuous to be shown in the extra window.
I think it's now burying the buffer, but doesn't delete the window.

Again, the desired behavior would be to remove windows (or frames) that were created to display the *Completions* buffer rather than to leave them visible.
