When loading a structure that includes a redstone wire on top of a crafter, the redstone wire breaks and a redstone dust entity is left in the world.

Steps to reproduce (Creative mode):
1) Place a crafter and a redstone wire on top
2) Place and configure a structure block for the 2-block high column
3) Save the structure and load it in another location

Tested in 1.21.1 and 24w39a snapshot

Just to clarifty, it's an issue with the Crafter, and not the Crafting Table.
