@0x416e746f6e Thanks for the PR, can you please add a file under the changelog directory with a short description of the fix. Thanks!

Good with this change other than the changelog that @garethgreenaway requested.

[Ch3LL]

Since it was a small change, I went ahead and added a changelog file and migrated the test to the pytest directory.

@garethgreenaway would you mind re-reviewing?
