Add object override for rectangle objects

[dcronqvist]

Description

Due to not having an OverrideObject overload for rectangle objects, they would get stuck in an infinite recursion when performing overriding from templates. This has been fixed by adding a corresponding overload, and adding a test case map to make sure we do not regress.
