Motivation for this change

https://nix-cache.s3.amazonaws.com/log/gj2vn41aa7ccl3frmkcvssn4na8z3ngm-python3.8-agate-excel-0.2.3.drv
ZHF: #122042

I git bisected the failure, and pinpointed it to a bugfix in a dependency bump. I filed a ticket with upstream. Based on my read of the openpxyl issue, I determined that this failing test was probably erroneous, so I disabled it.
