OSX shortcut for "Move focus to next window in active application" (see System Preferences > Keyboard) 
does not work as expected in some cases.

Test case:

Open 2 documents, one must contain a list.
The OSX shortcut properly navigates through the 2 documents available from the "Window" menu.
Move the cursor to the list in the document that contains it.
A floating menu appears.
Now, the OSX shortcut navigates only between the document containing the list and the floating menu. 
It is not possible to access the other document through that shortcut.

There are 2 issues:
1) the floating menu should not be considered as a window, only the items listed in the Window menu 
should be accessed with this shortcut
2) even if the floating menu is accessed, the shortcut should not be limited to the document that 
triggered the floating menu and should access all the other available document.
