I would side with @Loak van Vucht

This report is invalid in my opinion, otherwise the non- waterloggable doors would be a bug too

can confirm for non-optifine 1.16.5  

@Adan Chappuis Ideally remove the 'optifine' bit

"In addition, this is different from the standard weight of 5 in (most) ocean type biomes."
This part is apparently intended though, to combat the issue of there being significantly less spawning spaces in rivers, compared to oceans.
 

May I suggest for the title to include 'horizon' or 'black horizon'?
I was just about to report the issue, as I didn't find this ticket before, and was pointed here by a helper on the discord!

For everyone that is interested in this issue, it is a duplicate and I would encourage you to vote for the original bug report! 😉

@Mark Derickson I just came across MC-197647 that is the reason why I came to check on this page again.
My report seems to dublicate it, but I find my title a bit easier to understand.

Edit: This is also the reason why I didn't find MC-197647 in the first place.

The fix of this has led to players not being able to step down a block while sneaking with a block above the head (MC-209925).
You now need to mine the two blocks above, and to the side of the player to jump a full block up and then fall two, onto the block you wanted to get to.

It probably conflicts with the fix of this bug and will therefore probably from now on be seen as intended behaviour.
