Next steps on emoji picker performance

Description

We still experience lag when opening the emoji picker (1-2 seconds before it becomes responsive to the mouse on hover), and when hovering the mouse over emoji in the picker the hover effect is visibly chunky

What are next steps to get a smooth emoji experience? Can we pre-load the picker so it's instant? See Discord as an example of a very responsive picker:
