Research direction

Start with the reported setting.json keybinding using , f, and editor.fold, then reproduce it on VSCodeVim 1.24.1. Use the supplied stack trace to trace the command execution path and determine why this binding raises the constraint error. Done means the binding executes without the reported error.
