Upon exiting the boat while its moving/brushing against a block, it will remove your ability to attack

While looking for loot in the ocean, I exited my boat while moving and lost the ability to attack, and use my shield.

I created the world in 1.15.2
Played the world in 1.15.2,.1.6 Pre-Release 1, 1.6 Pre-Release 2

What I expected to happen:**
     Exit the boat allowing me to kill the drowned and defend myself against tridents
What Happened:
     I exited the boat and slapped around until I realized what happened
What fixed it for me:
     A quick Game relog

How to Recreate it:
     Step 1: Obtain a Boat.
     Step 2: Place the boat on water or land.
     Step 3: Enter said boat and move forward/around continuously .
     Step 4: Exit the boat while still moving forward/around.

This does happen after everytime I leave the boat, but enough that it is a annoyance.

Notes: I used a backup after I loaded the world in 1.15.2.
>Created World in 1.15.2

>Loaded 1.16 Pre-Release 1 (Made a backup beforehand)
>>Played for a little bit
>Loaded 1.16 Pre-Release 2 (Made a Backup beforehand)

>Used Backup save.
>>Re-loaded game back in 1.16 Pre-Release 2
>>>Played until I encountered the bug
