Description: The "minecraft:icon":{} component introduced in a recent beta made it so its contents and additional parameters are handled on the server as opposed to the client (how it is in 1.16.40). This change has serious flaws and what I believe to be unintended consequences as it relates to icon animating and reusing the same texture. 

Expected behavior:  when using the minecraft:icon component, creators can call their own molang animation scripts from their own resource packs (for server and multiplayer use) without the need for it to be made on the server. This would allow a much wider array of client-side customization that resource pack makers have to miss out on with the current way this component is set up server-side.

Actual behavior: the minecraft:icon component is handled on the server only and gets the animation script from the server, and clients cannot customize the animation for their own personal resource packs, severely limiting creativity.
