On All of fabric 3 Even when im breaking grass in the jungle onions dont drop

I'm in the AOF discord and people regularly talk about getting onion seeds, some of the modded biomes don't seem to be categorized correctly, so some jungle biomes aren't actually jungle biomes. I might be looking at changing this for 1.17 but I'm not sure what I'll do yet

There is a rainbow jungle biome from terrestria that will drop them, vanilla jungles will drop them, but ecotones jungles are apparently considered plains.
