> However, subsequently evaluating (frame-parameter nil 'fullscreen)
> returns nil, so that in step 2, the frame-parameter is (again) modified,
> though the frame is already maximized.  Now, however,  evaluating
> (frame-parameter nil 'fullscreen) returns `maximized', so in step 3, the
> frame is now demaximized.

> I executed modify-frame-parameters with a couple of other frame
