No window decorations on Wayland with window placement set as maximized
### System
- Inkscape 1.4.4
- Plasma 6.6.5
- Kwin 6.6.5
- Linux -> Arch Linux -> Zenned
### Steps
- Log into Plasma Wayland.
- On (System Settings -> Window Management -> Window Behavior -> Advanced) set "Window placement" as "Maximized".
- Go to (Inkscape -> Help -> About Inkscape)
### Result
The window has no borders, and moving it is not possible.
### Root
As said in the [Kwin report](https://bugs.kde.org/show_bug.cgi?id=499256):
The app tells Kwin about the new window, but it doesn't set any useful hints to let Kwin know that the window cannot be maximized. The app makes up its mind quite later after Kwin has already sent a configure event.
Furthermore, the app must obey the size that Kwin tells it to resize to in the maximized state, the app cannot pick its own size, it has no other choice than follow the size the compositor asks it to use.
According to the xdg-shell spec, the app should have been disconnected (Kwin is more permissive though).
