False negative: "being bias" not flagged

This common error was addressed in #3058 but I've just come across an instance not getting flagged in a YouTube comment:

> since this judge is refusing to do their job by being **bias** they are actually violating their own legal oath and these judges need to be held accountable for their own corruption

Start by reviewing issue #3058 and tracing how the existing “being bias” detection handles the example sentence. Reproduce the YouTube comment case, then confirm that equivalent uses of “being bias” are flagged without breaking the behavior addressed in #3058.
