1.17 Bugs about compost bins

I found the compost bin underground while I was playing minecraft (java) and accidentally placed sand over my head

When you are swimming in a compost tank, you enter a perspective-like state. If there are no blocks around the compost tank, you can see the outside of the compost tank, and when there are blocks, you can see the caves underground. I think it's a bug, so I'm here to react and hopefully deal with it, thanks
