Riptide Block Glitch

Accidently filed under BDS, I have now redone this under MCPE

Steps to Reproduce:
1. Get a trident
2. Enchant it with Riptide
3. Stand up against a one-block high wall/concave corner
4. Wait for rain
5. Launch the trident directly below you into the ground.

Observed Results:
The player goes on top of the one-block high wall

Expected Results:
The player should stay in the same place.
