Unity Issue Tracker - Scripts with null Components on GameObjects are not removed when calling GameObjectUtility.RemoveMonoBehavioursWithMissingScript

Looking at the user project, the references in the scene file is of type "MonoScript". MonoScripts tends to be serialized into a scene file for: - Special case MonoBehaviours, authored by Unity, with a native backing (e.g. Entity’s SubScene) - Script references from Unity 4.x and older We couldn't figure out how these references ended up in the scene file in the first place, but the assembly name points towards that these were somehow created by the user. The GameObjectUtility.RemoveMonoBehavioursWithMissingScript-API is created to remove MonoBehaviours from GameObjects which are missing their script file. Since the GameObject has a MonoScript, not a MonoBehaviour, the API is not suitable for this type of action. If we find out how these MonoScript references were added to the scene file, do file a new bug report, so that we can take a closer look at it with updated repro steps.

How to reproduce:
1. Open the attached “IN-142438“ project
2. Open the “scene“ scene
3. In the Hierarchy, select the “background“ GameObject
4. In the Inspector, observe and note the Components of the “background“ GameObject
5. In the Editor menu bar, select “GameObjectUtility“ (RemoveNullComponents > GameObjectUtility)
6. Repeat steps 3 and 4

Actual result: The (Script) null Component has not been removed from the “background“ GameObject
Expected result: The (Script) null Component has been removed from the “background“ GameObject

Reproducible with: 2023.1.0a1, 6000.0.74f1, 6000.3.15f1, 6000.4.6f1, 6000.5.0b7, 6000.6.0a4

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Note: Testing 6000.4 to 6000.6 streams required minor adjustments to the script calling GameObjectUtility.RemoveMonoBehavioursWithMissingScript because of the changes made to EntityID
