Clipping through blocks

I found a way to clip through a trap door, fence , and a bell you can literally walk right through them besides the trapdoor which you need a staircase but tbh I like the trapdoor bug cause it's cool for hidden bases. but this got around 7 of my villagers killed randomly by suffocating in walls. They also get stuck on chests, beds, and glitch inside bells for a very annoying noise
