I’ve created a test plugin to familiarize myself with adding custom emoji. During the process, I decided to add quite a few emoji (most everything from fontawesome) as an exercise. The plugin can be located at: GitHub - SGColdSun/fa-emoji
Everything worked as intended initially. Went out to dinner, came back a few hours later to find that the emoji in past (and new) posts only displays correctly in the topic title, and the preview. The body of the message (once submitted), displays the emoji for a second or two before it defaults back to the :emoji-here: text.
An example of the issue can be seen here:
There is no errors in the log. No related errors in Google’s dev console.
