The Bug:

Simultaneously pressing the "Walk Forwards" and "Walk Backwards" keys while riding and controlling a boat moves the boat forward.

When simultaneously pressing "Walk Forwards" key ("W" by default) and "Walk Backwards" key ("S" by default), movement is normally stopped, however, when riding a boat, this isn't the case. It's important to note that when simultaneously pressing the "Strafe Left" and "Strafe Right" keys while in a boat, the boat doesn't move.

Steps to Reproduce:

1. Simultaneously press the "Walk Forwards" and "Walk Backwards" keys and observe how you don't move as expected.
2. Enter a boat and once again simultaneously press the "Walk Forwards" and "Walk Backwards" keys and observe if you move or not.

Observed Behavior:

The boat moves forward despite both the "Walk Forwards" and "Walk Backwards" keys being held down.

Expected Behavior:

The boat would remain still.
