Research direction
Start with src/actions/commands/commandLine.ts at the reported failure, then trace the callers in src/actions/base.ts, src/mode/modeHandler.ts, and src/transformations/execute.ts. Reproduce the error with VSCodeVim 1.23.2 and determine the state that causes the unexpected mode; done means the key no longer raises this error and a regression test covers it.
