Placing an instance on top of another then undoing resets the original instances properties

In this case I noticed it resets the instances rotation value. To reproduce the problem[

1. find an instance that has a rotation value other than 0 (beach tiles are a good example)

2. insert a new instance on top of that one

3. undo

You will notice the origial instances rotation value will be reset to 0 and will not look right.
