Research direction
Investigate how preprocessor errors are currently handled in Karma's runner. Look at the preprocessor plugin interface and the runner's output capture mechanism. Check if error events are properly emitted and listened to. Consider modifying the runner to display preprocessor errors in the same way as test failures.
