AFAIU, it depends on the Emoji.  The sequence of Emoji+VS16 should
take the same width as the Emoji itself.  The Unicode file
EastAsianWidth.txt gives the width of each character; you will see
there that some Emoji are full-width characters (take 2 columns) while
others are half-width (take 1 column).  The Variation Selector doesn't
(or shouldn't) change that.
