You can't open the boat with chests without a shift, even when you can't get into the boat (when the place is occupied by a mob or a player). This does not match the bedrock version where you can open the boat's inventory without using shift when there is a mob/player in the boat.
Steps to reproduce:
- Place the boat with chest.
- Put the mob in the boat with chest.
- Try opening the boat's inventory without shift.
The boat's inventory does not open without shift, even if the place in the boat is occupied.
The boat's inventory will open without using a shift when a mob/player is in the boat.
