Test Executions List report won't load when sorted by Test Plan

Steps to reproduce:

1. Go to the Test Executions List report and generate it.
2. Add the column 'Xray Test Plan' to it.
3. Click on the header of the 'Test Plan' column to sort the Test Executions by the Test Plans.

Expected result:

The report should reload, displaying the Test Execution issues and sorting them by the Test Plans to which they are associated.

Actual result:

The report will never load completely, getting stuck at 99%:
