Items in waterlogged stairs don't float up high enough to be caught by a water stream above the stair
I was making a sugar cane farm made by TangoTek on YouTube. When trying to use a water stream with all source blocks with a waterlogged stair at the end with a water stream above it, the item caught in the stairs flows up but is not caught by the water stream above it. This bug is only present in 20w22a and 1.16 Pre-Release 1, as it works in 20w21a and before just fine.

I'm fairly certain this is already tracked in MC-187392 - please let me know if that is incorrect.

Confirmed. For easier reproduction, I've attached a screenshot of my test setup. Waterlog the stair and throw an item inside of it. It will flow upwards and be caught by the item stream in 1.15.2, but it will stay there inside of the stair in 1.16-pre1.
