Overview

The issue is that the victory-hand emoji default skin tone when used directly (✌️) does not match with the result from applying the none skin tone to the victory-hand of another skin tone.

Steps to reproduce

Two ways of testing this:

1. The following test added to the code base will fail:

t.is(skinTone('✌🏻', 'none'), '✌️');

(outside of code block render):
t.is(skinTone('✌🏻', 'none'), '✌️');

2. The following code (remember to init an npm project, and have "type": "module":

import skinTone from 'skin-tone'

function compareEmoji (emojiOne, emojiTwo) {
  return emojiOne === emojiTwo
}

console.log('victory-hand match:', compareEmoji('✌️', skinTone('✌🏼', 'none')))
console.log('ok-hand match:', compareEmoji('👌', skinTone('👌🏼', 'none')))

The result of step 2 is:

node victory-skin-tone.js
victory-hand match: false
ok-hand match: true

Expected result

The victory-hand default skin tone when pasted should be matched successfully against the 'none' applied skin tone.
The ok-hand successfully matches using the same manner, where the victory-hand fails.
