Comment (by pento):

 In [changeset:"41046"]:
 {{{
 #!CommitTicketReference repository="" revision="41046"
 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
 [41043] 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.
 See #35293.
