Thank you!

Could you please add a comment about this in the code.

If really needed, we can make this customizable.

When saving we will have to establish a relationship between each
minibuffer-less frame and its associated minibuffer frame.  When
restoring we first have to create the minibuffer frame(s) and then
create the minibuffer-less frames and redirect them to their minibuffer
frame(s).  When at this time a normal frame (with minibuffer window)
remains, we probably have to delete it - AFAIK there's no function to
convert an existing minibuffer-equipped frame to a minibuffer-less one.

I think anyone needing such an arrangement will have to write the
appropriate code.  Here we only have to make sure that (some sort of)
frame names can be written by desktop so we can use them later when
restoring the frame/minibuffer relationships.

Is it possible that you call `desktop--make-full-frame' too "early", in
some sense?  Does maximize have the same problem?
