Summary:

A block-aware teleport command succeeds when teleporting into the collision box extension of a fence (the half-block-tall collision box on top of the fence).

Impact:

This is unexpected behavior and may not be desirable.

Repro Steps:

1. Open a world.
2. Place down a fence or a wall block
3. Point your crosshair at the top face of the fence
4. Use the /tp command and autocomplete the coordinates to where you're looking. Set the last argument to 'true'.
5. Run the command.

Observed Results:

The command succeeds teleporting you into the fence, before the fence pushes you out.

Expected Results:

The command should fail and you shouldn't be teleported.
