The last run status on a Test Set can be confusing, especially for a newbie like me :)
I started a test run, some tests failed and I ended the run
Run History shows status = failed (good and accurate)
Test set list in right nav shows failed (good and accurate)
I started the test run again, did not End Run, just Save & Close
Run History shows status = In Progress (good and accurate)
Test set list in right nav shows failed (not current, not accurate and confusing)
