If I do an operation like "send to back", followed by "undo", it undoes the previous change. Steps: 1. Go to a map with overlapping objects 2. Perform an action (e.g., move an object) 3. Select an object that overlaps another (so there's a visible effect) and choose "send to back" 4. Choose "undo" Expected result: The "send to back" operation would be reversed. Actual result: The move operation is reversed and the layer change remains.
