      While placing blocks, it's possible to swap hands at the perfect time to avoid placing a block, causing the player to sometimes walk off a block when in a crouched position.

      Notes:

      • It seems to be a timing issue, so it doesn't happen with each block
      • It doesn't appear to be directional, reproducible in each
      • Swapping with two stacks of blocks doesn't cause the player to fall
      • Happens if pressing instead of holding buttons down as well
      • When it occurs, the block place is cancelled? It temporarily appears and disappears
      • Unconfirmed: Only happens on primary -> offhand swaps?

      Steps to reproduce:

      1. Hold blocks in a single hand
      2. Place blocks while repeatedly swapping hands
