Passrate: Show the list of issues that affect the runrate the most, not just the passrate
Some issues may have a rather limited impact on the passrate, but have a rather dramatic impact on the run rate. For example, if the test 1/50 forces the run to be aborted, then its impact on the passrate will be 1/50, but its impact on the runrate will be 49/50.
Making such issues more visible in the passrate view would help bug prioritization and lead to these issues being fixed much faster.
This might have some ties with #2.
