Research direction
Start by reproducing the error when editing a .md file in VSCodeVim 1.24.1, then inspect src/mode/modeHandler.ts at updateView line 1647 and the extensionBase.ts callers shown in the stack trace. Done means the TypeError no longer occurs during editing; the issue does not name a test to run.
