How to reproduce:

1. Open the attached project and the only scene in it.
2. In the Hierarchy, select Banana/A/B and notice that B GameObject uses a Scale of 1,1,1.
3. Duplicate B GameObject.
4. Duplicate B(1) GameObject and observe that the second duplicated GameObject now uses a Scale value of 1.000001

Expected behavior: The Scale value should not change when duplicating a GameObject.
Actual behavior: Duplicating a GameObject twice, causes a change in the duplicated transforms Scale value.

Reproducible: 5.4.0f2, 5.5.0a4
Not reproducible: 5.3.6f1, 5.2.4f1
