Boats disappear when disembarking them

Since the new 1.17.40 update, boats just disappear whenever you disembark them.

Steps to Reproduce:

1. Right click on any boat to embark.

1. Press Jump or Sneak button to disembark.

Observed Results:
Boat completely disappears. Doesn't drop as an entity either, it's just gone.

Expected Results:
Boat should remain where you last were positioned before disembarking.
