Release Type: Git

Version: Latest

Platform(s): Windows editor

Describe the bug
Let's say you have a collection defined on one of your component:

public class MyComponent : StartupScript
{
    public List<string> MyStrings { get; set; } = new();
}

You then

1. Put that component in a prefab
2. Add that prefab to a scene
3. And add in a string to the MyStrings collection on that prefab in the scene.

The yaml for the component in that scene would look something like so:

MyStrings:
    0a0000000a0000000a0000000a000000*: MyDerivedString

Notice the override marker (*) at the end of the Id for that item.
Now, make any change to your source and reload the editor, the next time you save, the collection would be empty in the scene;

MyStrings: { }

To Reproduce
See above.

Expected behavior
Reloads without loss of data.
