Yes, I think it's a bug that completion doesn't behave as if you've
left and then re-entered insert mode.  That's a bit different than what
you mentioned about the vim behavior.

Worse than that, vi-repeat forllowing the initial insertion repeats
the accept-line from the end of the previous command, thus attempting
to execute the (usually partial) current command line immediately.

Clearly more is needed to properly set up the vi-mode state at the start
of the buffer.
