I actually know that this bug is tagged corrected but he is not. So to resume, if you are in adventure mode, you're unable to place a water bucket or a lava bucket on a block with the tag CanPlaceOn on the item.

What I expected to happen was...:
The water/lava have to be placed on the block

What actually happened was...:
The water/lava was not placed

Steps to Reproduce:
1. Give yourself a water/lava bucket with tag CanPlaceOn on a block you want (for example: /give @p minecraft:water_bucket{CanPlaceOn:["minecraft:prismarine"]} 1 )
2. Try to place the water/lava (For the example, on prismarine)
3. Observe
