The values order is not working for workflow "Status" in a Test Executions list of a Test Plan

The values order is not working for workflow "Status" in a Test Executions list of a Test Plan

How to reproduce:

1. Create a Test Plan
2. Create several Test Executions that belong to the Test Plan
3. Each Test Execution should be in a different workflow status
4. In the Test Plan, on the Test Executions section, try to sort by workflow "Status"
5. The Test Execution list order is never changed since the button has no effect
