The changes look good to me. Is there a test associated with this already? If not, you can take the code from the issue you reference, turn it into a test, make sure it fails before this change, and make sure it passes after the change. |

Did it fail before this fix? (Ideally you want to write a test that fails before your fix, and then passes after your fix) |
