This was fixed in 2018 by this commit, I think.

    execute-extended-command: Skip waiting in more cases
    
    * lisp/simple.el (execute-extended-command): Don't wait when
    there's no binding the current command, and the user doesn't want
    to see "shorter" suggestions, or TYPED is nil anyway.

Skimming this thread, it's unclear whether there was anything else to
fix here.  Can this bug be closed?
