If you waterlog a block (including light_block), and then reset it with a structure block, It is still waterlogged

Steps to reproduce

1. Place a trapdoor
2. Save it with a structure block
3. Replace the trapdoor with water
4. Load the previous model with the structure block in same place

Observed result

     The trapdoor is waterlogged

Expected result

     **     The trapdoor is normal, just like how we saved it.
