The bug

MC-1133 was fixed in 23w18a, meaning that structure voids can no longer produce particles when fallen on from a height by falling on the edge of a different block. However, it's still possible to get them to produce particles by falling on top of them in other ways.

How to reproduce

1. Place a structure void
2. Place a boat in the structure void, or a carpet on top of the structure void
3. Fall on top of the carpet or boat from a sufficient height

Expected results

Falling on top of the boat would produce either no particles or particles of the respective wood type. Falling on top of the carpet would produce particles of that carpet.

Actual results

We get particles of the structure void instead.

How to fix

These would be fixed if MC-207949 and MC-261437 get fixed.
