I did some testing planning to open my own issue specific to honey blocks, but luckily found this one so I do not duplicate. But I will put what I found here anyway.

Java Minecraft 1.15.2

I put a honey block at -56, 56, 29. When crouch walking off the edge a player (and I assume any mob) can jump as though they were not on a honey block. I teleported myself right to the very edge of the block, at -55.88, 57.00, 29.999. (landing at y = 56.93750 if that matters at all) At that location the player's jump IS affected by the honey. But then I teleported to -55.88, 57.00, 30.00. At this location the player can jump freely uninterrupted from the honey block.

I did some more testing. I discovered some unrelated facts, like that the coordinates 29.99999999999999, 29.999999999999993, and 29.999999999999996 are all valid, but all other coordinates in between and after are rounded. Also all of these coordinates on the honey block from the last paragraph still affect the player's jump height as though you are an the honey block, so all is working as intended here.

I would suggest the player's hit box determine if it is affected by a block or not. This could break things in ways that I couldn't possibly think up, but obviously not all of the physics in this game work based on what is directly below Steve. If it did, we couldn't crouch walk off the edge of a block and hang onto it. I imagine that the same bit of code that tells the game not to fling Steve to the ground if you manage to get your center of mass off a block by .01 could help us out here. But I am only learning Java. Not yet worthy to be called a programmer, so I don't really know.

I experienced this issue once before in 1.14.[something] where several librarians disappeared inside my sweat shop. Today in 1.15.2 vanilla I noticed a master Fletcher that I had in my zombifying chamber had disappeared (it was safe at the time), along with 1 farmer and 1 mason both inside my potato/carrot farm disappeared. Screenshots added with chunk borders showing.
