Godot4 steals focus while moving other windows under i3

[unlessgames]

Godot version

4.1 stable

System information

Arch Linux with i3 window manager

Issue description

Under the i3 window manager on Linux, Godot 4 grabs the focus while moving other windows over it, this breaks the workflow on i3 (and possibly other tiling window managers like it) in an rather annoying way.

Below is a clip where the window on the left is moved towards the right over a godot window with the keyboard (Win+Shift+Right by default).

First one (green) is with Godot 3 which works as expected, the second one (red) is with Godot 4 where I start moving a window I want and Godot steals the focus mid-way and becomes the moved window itself.

Most likely related to #74378

Steps to reproduce

Use i3-wm and try to move something around a Godot4 window with keyboard.

Minimal reproduction project
