The path should generate out in the direction the jigsaw was pointing like it does in villages. Instead, it also generates out from the back as well as the front which can ruin some structures if you are creating a path away from something.
Steps to Reproduce:
1. Give yourself the following jigsaw block:
/give @s minecraft:jigsaw[minecraft:block_entity_data={final_state:"minecraft:structure_void",id:"minecraft:jigsaw",joint:"aligned",name:"minecraft:street",pool:"minecraft:village/plains/streets",target:"minecraft:street"}]2. Place the block facing any direction but up/down
3. Set the level over 1 and press generate.

Affects 1.21.4. Looking to request ownership to update/maintain it.
Updated command in 1.21.4:
/give @s minecraft:jigsaw[minecraft:block_entity_data={final_state:"minecraft:structure_void",id:"minecraft:jigsaw",joint:"aligned",name:"minecraft:street",pool:"minecraft:village/plains/streets",target:"minecraft:street"}]
May not be a bug/WAI, since the village jigsaw system uses old jigsaw settings before 1.16, which the name and target name are the same, using new jigsaw generating mechanics will cause such problem. Won't actually happen upon world generation.
