Interacting with the admin emoji API can lead to broken emoji
While trying to test the emoji part of the admin-fe, something I clicked created pack.json files for all local emoji packs that look correct but seem to result in the path being doubled, like in this example: https://pleroma.soykaf.com/emoji/blobcat/emoji/blobcat/blobbunnynomblobcat.png
Removing the pack.json files fixes the situation.
