Double-click on failed Test Results entry doesnt go to test code.

When I run tests for my project, the Test Results window shows which ones have not passed.  It used to be when double-clicking on one of those failed tests, the test code file would open in the editor. Now the code that opens is where the error happened -- most often this is in some rails core code and I have to examine the call stack to find which test it actually was.

Did this change on purpose, and is there a way to get back the old behavior?
