<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: Store the results of the `emoji_url` and `emoji_ext` filters in statics.
Previously, these filters were being run once per post, but the changes in <a href="https://core.trac.wordpress.org/changeset/41043">[41043]</a> caused them to be run once per emoji found.
We will not stand idly by while this kind of unfair performance penalty is placed on the emoji literate. The filters are now run once only, emoji aficionados everywhere can rest easy, knowing their posts will be just as performant as their emoji-less cousins.
Props ocean90 for noticing this severe oversight.
