### Issue description

When changing any property of tile source, e.g. name:

This error appears in the output:
```
UndoRedo history mismatch: expected 0, got 2.
Set name
```
It means that there is an undo action that starts with a global object and continues with a scene one.

Only happens when the TileSet is built-in and it makes the changes to the tileset being registered as global, i.e. not related to its scene (which results in history inconsistency after closing the scene).

I did some debugging and the action comes from inspector, which edits TileSetAtlasSourceEditor and then TileSetAtlasSource. I don't know what exactly triggers it; the properties should be only set on TileSetAtlasSource.

### Steps to reproduce

1. Add scene
2. Add tilemap
3. Add tileset (don't save it to a file)
4. Edit tileset
5. Add atlas source (e.g. drop icon.svg)
6. Change atlas name
7. Observe output
