      The bug

      When using a bucket in adventure mode, the logic that checks that the clicked block is listed in the bucket's CanPlaceOn tag is applied to the block behind the one the player clicked. For example, if the player clicked the top face of a block, the check is applied to the block below.

      How to reproduce

      1. /gamemode adventure
      2. /give @p water_bucket{CanPlaceOn:["minecraft:grass_block"]}

        → Clicking on a grass block that does not have a grass block behind it does not place water.
        → Clicking on any block that has a grass block behind it places water.

      3. /give @p bucket{CanPlaceOn:["minecraft:water"]}

        → Clicking on water that does not have water behind it does not pick up the water.
