The gap between 2 honey blocks ontop of one another is to small for arrows

I'm not sure that's a bug

Just did it. Between two Honey blocks in pillar. You just need to stand at the right height.

later I tried it and I succeeded this time but it is a very specific height you have to stand on. You also need to shoot it at a very specific angle otherwise it won't work.

Managed to shoot one through as well.
It's just a very tight gap.
It's easier to adjust yourself on the x/z axis and the arrow makes an arch, which also can make it hit the bottom or top of a honey block while trying to fly in between.

So albeit a bit harder, it is possible to get an arrow through.

Resolved as invalid, as it's just harder to shoot through since arrows fly in an arc.
