Request for updated example highlighting problem of mixing of AN and EN

The only concrete example I have found that justifies the prohibition of
mixing AN and EN is CS EN AN CS R in an LTR context.

The current bidi rules, plus changes from a subsequent email from Mark, an
AN will require the label to be treated as RTL
Therefore, a label mixing AN and EN will be treated as an RTL label.  The
above example (EN AN) will violate the first bidi rule, that label must
begin with L, R or AL.

Is there a concrete example that is otherwise IDNA-valid?
