ns-pop-up-frames and fullscreen

[Jean-Christophe Helary]

When ns-pop-up-frames is set to nil files are supposed to open in the existing 
frame.

When Emacs.app is not in fullscreen, you select a file, double-click it (or any 
other open command) and this triggers Emacs.app to come to the foreground and 
display the file contents in the existing frame.

When Emacs.app is in fullscreen, opening the file that way does *not* change 
the display to put Emacs.app into the foreground, so you have to manually move 
to the Emacs.app fullscreen "space" to *then* see the file opening in that 
frame.

Is there a setting I am missing? Is this the expected behavior or a bug?
