Test Runs Report with the TestRun assignee filter is showing the wrong entries

Test Runs Report when using the TestRun Assignee filter, is showing:

• Test runs assigned to that user (as expected)
• Test runs associated to the associated Test Execution (not expected)

 
Steps to reproduce the problem:

1. Create 2 Tests ("Test A" and "Test B")
2. Create a Test Execution
3. Assign that Test Execution to you
4. Add the 2 previous Tests to the Test Execution
5. Assign one of the Test Runs ("Test A") to you
6. Assign one of the Test Runs ("Test B") to another user
7. Go to the Test Runs Report and filter by TestRun assignee (you)
8. instead of showing only the Test Run of "Test A", you will see both "Test A" and "Test B"
