### Godot version

4.0.beta10 (d0398f62f)

### System information

Windows 11

### Issue description

When the Move Mode tool is selected (hotkey W), using the arrow keys will move a node a few pixels before causing the 2D editor to lose focus.

This does not happen when the Select Mode tool (hotkey Q) is selected. This also doesn't happen when you use shift + arrow key (but this moves multiple pixels at once).

This is also not an issue in 3.5 (new regression in 4.0).

### Steps to reproduce

- Open any scene in 2D mode.
- Select `Select Mode`:

- Select any CanvasItem.
- You can move it around using the arrow keys (1px at a time).
- Now select `Move Mode`:

- Try moving the node using arrow keys.
- Notice how the main 2D editor loses focus.

Some extra info: shift + arrow key works fine!
