So it would appear that your question is exactly as in the reference
you quoted, that ifupdown was configuring wlp4s0 when /w/n/i was
in place, resulting in NM displaying a question mark.
Thank you for confirming that this is not a bug.
I have no idea concerning GNOME in sid, but a KDE applet from nm-plasma
in bookworm is able to react to commands
ip link set enp0s2 down
ip link set enp0s2 up
in a VM when the only interface (besides lo) is managed by ifupdown.
When the interface is down, the icon changed to a dimmed one with a red "x".
I have not figured out how to determine state using nmcli or through
various objects reported by
busctl tree org.freedesktop.NetworkManager
E.g. nm-online always reports success. It might be some fallback in the
KDE applet. Depending on that it is either a bug or not in the GNOME applet.
P.S.
