They do, but when edebugging jump-to-register, I end up in this branch
of the cond:

     ((registerv-p val)
      (cl-assert (registerv-jump-func val) nil
              "Don't know how to jump to register %s"
              (single-key-description register))
      (funcall (registerv-jump-func val) (registerv-data val)))

Which ends up calling frameset--restore-frame, so the problem is elsewhere.

I think I tested the wrong thing, probably because I forgot an
'eval-defun' somewhere.

The code that causes the frame to be restored in the wrong place is

    (modify-frame-parameters frame
                             (if (eq (frame-parameter frame 'fullscreen) 
                                 ;; Workaround for bug#14949
                                 (assq-delete-all 'fullscreen filtered-cfg)

in framset--restore-frame, which means Iʼm going to have to break out
gdb and/or printf. (Iʼm surprised Eli is seeing this on MS-Windows
though, I thought the low-level frame implementation was completely
