Issue description

I'm working on a new plugin to build by procedural nodes via visual scripting and build my own custom graph nodes.
As example:

To have the same Look&Feel I rebuild the property editors used by the Godot editor inspector. (The original property editors are not public, but why?)

I used the Godot provided class EditorSpinSlider
And it works fine, so far so good.

But i have a unit test coverage and it fails when loading my ui components by error

Parser Error: Native class "EditorSpinSlider" cannot be constructed as it is abstract.

From the documentation, it is not abstract.
This blocks me actually to develop and test the scene and often needs a restart of the Godot editor.
It also blocks me to write unit tests because the scene is loaded via a test API and not instantiated by a plugin.

Steps to reproduce

Use the attached example plugin.
When the project opened, it shows the example in the bottom.

The scene is loaded and the custom panel using the EditorSpinSlider works fine.
But when you try to run the panel scene itself, it fails with the error.
Parser Error: Native class "EditorSpinSlider" cannot be constructed as it is abstract.

This makes it impossible to test the scene manually or by a testing framework.

Correct me if I'm wrong, but I think it's because EditorSpinSlider, being an editor control, is only available when running inside the editor, so they cannot be constructed when running the scene as a game.

Probably the same issue as #73525.

Yes is described as editor control, but creating a scene and running it for testing makes it impossible if it is recognized as abstract.

Consolidating in:

• EditorExportPlugin raises error everytime you run the game with F5 because of "abstract native class" #73525
