The Bug

Maces and tridents show a small part of their sprite in the player's hand while rowing a boat. Ordinarily, rowing a boat should hide the items the player is holding completely, however, a few pixels of the Mace and Trident still show nonetheless.

This also affects certain custom items as PotholedSea40 has stated, however it is not included in this bug report since it isn't vanilla.

Note: This bug report was originally only about the Mace.

How to Reproduce

1. Hold a Mace/Trident in your main hand while rowing a boat (holding the forward key).
2. Note how the weapon will still show in your hand very slightly.
3. Placing the weapon in your offhand will also show a bit of itself.
