Stairs and slabs above water create hacked water even though they aren't in water
What I expected to happen was...:
Stairs and slabs to be above the water without interacting with the water in any way
What actually happened was...:
Stairs and slabs have hacked water in them which causes weird rendering
Steps to Reproduce:
1. Put slabs and stairs in the block above water sources

I do think that fixing MC-125216 would also fix the problem you're having. It looks like it's the same issue even though slabs are placed above water in this case.
I think this should be reopened as MC-125216 is about the rendering of hacked water, whereas this is about the stairs and slabs above water incorrectly having hacked water when they shouldn't. This does also cause rendering as in MC-125216 but is a different issue.
