This occurs on 3.5.2 as well.

### Steps to reproduce

- Enable `Show Hidden Files` property in the Editor Settings:
    - Reload Godot for the bug to occur
- Create a FileDialog node, and set it's `Show Hidden Files` property to false
- Save and close the scene, and reopen it
- The `Show Hidden Files` property is reset to true.
