The test cases under TestPandasSetitem.test_setitem_series() fail on Pandas 1.3.0 due to pandas-dev/pandas#42437.

These tests create a Series of dtype object and attempt to assign a TensorArray to that series. They fail because Pandas passes the TensorArray through numpy.asarray(), which turns the TensorArray into a 2D ndarray instead of a 1D array of ndarray objects.

Users should be able to work around this issue for now by explicitly casting TensorArrays to dtype of object, then performing the assignment.

Keep this issue open until the upstream bug is patched, then re-enable the tests, then close this issue.
