      Description

      The bug

      In some situations the player stops blocking with a shield client-side and therefore can attack again, but server-side they are still blocking. This allows them to attack and block at the same time, which should not be possible.

      How to reproduce

      1. Hold a shield in any hand and block with it
      2. Deflect an arrow with it, observe that the shield moves as it loses durability
      3. During the movement, without releasing the right mouse button, hover over any container (I've tested with a dispenser only, but believe it works with every one)
      4. Before the shield returns you access the container, now you can release the right mouse button
      5. Upon closing the container UI you are no longer blocking, but the blocking effect persists (you still deflect arrows and the shield still loses durability) until you right click again.

      While the effect of blocking persists, you can attack normally as if you weren't blocking.

      This can also be reproduced by blocking while entering a nether portal (see MC-183694).
