Start with the stack trace entry points in the bundled out/extension.js, especially getLine and getCurrentParagraphBeginning, and reproduce the failure using VSCodeVim 1.18.9. Identify the command or key sequence that reaches the invalid line value; done means the reported operation no longer raises the illegal line error.
