F39 Rawhide: GNOME on XORG: Legacy applications have Windows title bar different than Native Gnome Applications

Start with last rawhide iso: (Fedora-Workstation-Live-x86_64-Rawhide-20230503.n.0.iso) set password to user liveuser an logout. Login with liveuser and select "GNOME on Xorgs", open libreoffice or firefox and nautilus or gnome-termonal. The title of firefox is different than Nautilus. Also the Middle-Click mouse button, set to "lower" via gnome-tweaks, if pressed on title bar DO NOT WORK on legacy windows.
