Theme overrides have a bugs

Godot Version

4.5.1 rc2

Question

How do I receive prompts when using the ‘theme overrides ’ feature:

Toggling the checkbox is disabled for Resource properties. Modify the property using the resource picker instead.

Click on the “StyleBox” dropdown rather than the checkbox. The UI for themes is kind of counterintuitive. Clicking on the dropdown gives you a list of things, and if you pick one it will check the checkbox and use what you clicked on.

I had the exact same issue, I followed the advice to make the selection and the checkbox does get checked again but the properties that should be showing once the checkbox is checked don´t appear as they should.
