### Godot version

Godot 4.0 RC1 

### System information

MacOS Ventura 13.2

### Issue description

When in the "Text Editor" Help section and trying to change either the:

* Help Font Size
* Help Source Font Size
* Help Title Font Size

Changing the font size has zero effect on the font size.

See below example where "Help Font Size" is 40 however this does not reflect in the godot docs.

### Steps to reproduce

1. Open Editor Settings
2. Click on "Help" within the "Text Editor" section
3. Change the font sizes (Help Font Size, Source Font Size, Title font size)
4. Close the editor settings
5. Observe that changes to the font size had no effect on the font size within the editor godot docs text.

Even restarting Godot has no effect on the font size within Help.
