30.0.50; unable to change to raise or lower a child-frame |

Hello.
I'm working on an alternative windowing system for Emacs that explores
child frames as a base for windowing, instead of using splits. I've
noticed that no matter what I do, I can't restack child-frames. Calling
`frame-raise' or changing the `z-group' has no effect on the frames
spawned by my window manager.
The simplest possible way to test this in Emacs -Q is to eval this code
twice:
(let ((frame
(make-frame
`((width . 20) (height . 8)
(parent-frame . ,(selected-frame))
(drag-with-header-line . t)
(undecorated . t)
(minibuffer . nil)))))
(set-window-parameter
(frame-root-window frame)
'header-line-format
" %b"))
It will create two small child frames, and no matter what I do the order
of frames is not changes. A friend of mine reported that it works under
X on Emacs 28 as expected. I suspect that it may be related to the fact
that I'm using Wayland version of GNOME Shell and a PGTK build. I will
try to recompile Emacs later and post the results here.
The window manager can be obtained here[1] if you want to experiment with
it but the snipped above should be sufficient.

It seems like this is not something we can fix in Emacs, so I'm closing
this bug report now.
If this conclusion is incorrect, please reopen the bug report.
