after exiting a boat, no more interaction possible with it

after exiting a boat, it is no longer possible to interact with it.

What I expected:

When exiting a boat, expected to be dropped in the vicinity, the boat still floating. I then expected to be able to push it around in the water, or right-click it to re-enter, or left-click/destroy it to drop the item.

What happened:

Instead either me or the boat was dropped some distance away, usually
about ten-ish blocks. The boat was usually still floating, making up-and down movements, but when I approached it again it proved to be immobile, no longer responding to clicking or touching. Instead I could position myself on top like any non-liquid block.

Steps to reproduce it:
1. use a boat
2. exit the boat via left-shift
3. position yourself in the boat's vicinity
4. enter the boat's position or click it
