Fall damage being taken in 1x1 areas

Hello,

I am having this issue in which falling down a 1x1 hole into water, landing on slime or landing on hay bales causes fall damage on the player (I do know that hay bales only reduces damage). I can only assume it's to do with the player glitching into the blocks beside the water or slimeblock and the fall damage is taken when the player comes to a stop, but I am unsure if that is what is really happening. This bug has caused me and my friends many issues. (We were playing on a world today and my friend was really far away. He jumped into water and died due to blocks being beside him when he hit the water.)

I am unsure whether this is intended or a bug but it's really annoying and I hope it is fixed soon.

Thank you.
