Documentation
If non-nil, try making the control frame be floating rather than tiled.
If your X window manager makes the Ediff control frame a tiled one, set this to a non-nil value, and Emacs will try to make it floating. This only has effect on X displays.
This variable was added, or its default value changed, in Emacs 30.1.
Probably introduced at or before Emacs version 30.1.
