Emoji and sticker favorites do not sync between mobile and desktop

Observed behaviour

Mobile and Desktop/Web Emoji/Sticker favorites appear to be completely separated at the moment. A favorite on one platform does not reflect on the other.

Reproduction steps

On mobile, long-press any emoji or sticker in the emoji menu and favorite it.
Note that on desktop that favorite will not appear.
Do the same thing in the other direction, same result.

Expected behaviour Emoji/Sticker favorites should sync. Since they seem to sync between desktop and web clients, I feel confident that syncing is intended behavior.
