Why are sometimes some emojis missing in chat?

Sometimes chat does not show all emojis.


Steps:

  1. type “:clo”
  2. click “more”
  3. remove the emoji search query
  4. notice that these aren’t all emojis

For comparison, here are the two different results: First, the one at the end of the video, when you followed the steps, and second, all emojis as they are shown when you, for example, click the emoji button (In the first screenshot, :rofl:, :smiley:, :sweat_smile:, and :laughing: are the first ones that are missing)
