Loading structures with less than full structure integrity loads nothing or everything

The bug

If you are loading a structure from a structure block with a structure integrity that is less than 1.0, regardless of seed, it either loads every single block or no block at all.

How to reproduce

Use the following command and load the structure

/give @s structure_block{BlockEntityTag:{mode:"LOAD",integrity:0.5f,name:"minecraft:end_city/ship"}}
