AdminFE only allows for example mogrify items to be selected, would like to use resize_to_limit

I'm confused why in AdminFE in the Upload section, Pleroma.Upload.Filter.Mogrify doesn't allow me to set a resize_to_limit - it doesn't seem to accept any input outside of strip, auto-orient, and {"implode", "1"}

I'm trying to set {"resize_to_limit","1920x1280"}

Am I doing it wrong by trying to do use resize_to_limit this way?
