Summary
Inherited getters were not enumerated by
deepCyclicCopyObject
causing getters not being replaced with value and the test code to call those getters later on the copied object. If the non-replaced getter depended on other non-copied value, e.g. a private class field the calling code could end up in error while trying to show comparison of the expected and received value on test failures.Fixes #10167

Test plan
Added a new test case
'copies value of inherited getters'
which is failing without the fix but passes after.
