title: Python pdb function step/call shows no symbols: <string>(1)function_name()
body: <p>When stepping into pdb (via a set_trace), accessing another function (in the same file or a different file) than the one it was called in causes it to stop showing local symbols and context.</p>
  <p>How do I get the actual context/symbols to properly show up?</p>
