<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Emoji: Update Twemoji to 2.5.0.
Twemoji 2.3.0 has a rendering issue in Safari, emoji can sometimes be followed by U+FEOF (which is just a flag meaning "render the preceding character as emoji).
Twemoji wasn't catching this character correctly, and Safari rendered it incorrectly.
Twemoji 2.5.0 resolves this issue.
Fixes <a href="https://core.trac.wordpress.org/ticket/41584">#41584</a>.</pre>
