Undoing a sprite move in map edit mode also resets map zoom

[nighca]

Background

There is a bug in the map editor undo behavior.

When editing a project in map edit mode, undoing a sprite move can also reset the current map zoom level. That part is unexpected.

Reproduction

1. Open a project in the editor
2. Enter map edit mode
3. Zoom in the map
4. Move a sprite to a new position
5. Trigger Undo

Actual behavior

• The sprite position is reverted
• The map zoom is also reset back to the default scale

Expected behavior

• The sprite position should be reverted
• The current map zoom level should remain unchanged

Notes

Undo should only revert the sprite position change. View-state such as the current map zoom should not be reset as part of that operation.
