Maybe, I'm not sure.  There's this note in the comments to
x_highlight_frame member:

  /* The frame which currently has the visual highlight, and should get
     keyboard input (other sorts of input have the frame encoded in the
     event).  It points to the X focus frame's selected window's
     frame.  It differs from x_focus_frame when we're using a global
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
     minibuffer.  */
     ^^^^^^^^^^

How is (or should be) the mode line displayed when input goes to a
"global minibuffer"?
