Project icons aren't applied when debugging inside the editor [wayland]

Godot Version

4.x

Question

Godot 4.x projects don’t debug in the editor with the project icon applied but Godot 3.x projects do.

Project icons render correctly under the project manager:

Environment: 4.6.1 Debian GNU/Linux 13 (trixie) 13 on Wayland - Gnome 48

I’m aware that for exported projects on Linux, creating a .desktop file is required.
