[MCPE-220112] Vibrant Visuals not working in multiplayer

Whenever I turn on Vibrant Visuals, and then somebody joins (couch co-op) the shaders go away, but when I join back, they come back.

Linked issues

This is working as intended per the 1.21.80 changelog:

Splitscreen is not supported with Vibrant Visuals and the game will switch to Fancy or Simple rendering if multiple players are joined locally.

Will splitscreen be added to Vibrant Visuals? I want to play it with my friends.
