I think your expectations are incorrect, because they are based on
assumptions that are generally false in Emacs.  In particular,
depending on the context of the completion, typing more stuff after
selecting a candidate is what is actually needed, so ignoring that
would break valid use cases.

Therefore I think we will have to agree to disagree on this one.  I
see no bug in the behavior you described.  If it looks misleading to
you, you will have to get used to it.
