Editing a BlockCode breaks editor 3d first person navigation

[Cafezinhu]

What Happened

When a block script is opened on Block Code tab (by creating a new BlockCode or clicking "Open Block Script"), you can't use the editor's first person controls on a 3d scene.

How to Reproduce

1. Add a BlockCode node
2. Go to the 3d tab
3. Hold right click and press WASD

Operating System

Linux Mint 21.3 Cinnamon, Godot 4.2.2

Anything else?

Removing InputMap.load_from_project_settings() from _get_input_blocks()method in category_factory.gd script and reloading the editor stops the issue.
