ReLiC38

Further testing,

Tridents disappear regardless of the face they are thrown on (top, bottom and all four sides).

I verified that the tridents status using commands to make them say 'hi' in chat if they are loaded.  Tridents were responding until I moved more than 16 chunks away. (Sim 4, render set to 8)

Tridents thrown on top, side, and bottom faces will remain in the world if the player relogs near to them (in my test, I logged out and back on in the same chunk they were thrown).  After relog the one on the side face fell to the ground below, the one on the bottom face is floating a half-block below the face.  This behaviour is similar to how they behaved on 1.17.11 and prior.

OK, I threw six tridents on a raised solid-block platform with two air blocks underneath, then another layer of solid blocks.  All six tridents disappeared when I moved ~200 blocks away and returned.  They do not appear to be clipping through the floor.  If they are, I would not expect them to clip through the second floor,

Strange, because if they are clipping through the floor, would they not just fall into the air space blow?  I have an open area below where mine was thrown and it was not there when I checked.  Testing this in a flat world should be easy, throw the trident on a raised platform instead of on the base ground level.

This change basically breaks any minecart mob-mover that dumps the mobs into a hole, as the minecart will not drop them into air.  It would rather put them into a solid block to suffocate.

For boats, when you dismount in open water, you fall through the boat.  Previous version would let you stand on the boat.

There is no beneficial change to dismounting a strider. you usually end up in lava unless you are right next to a block you could have rode the strider onto anyway.

This change seems unnecessary, was there a need for it???  What bug report was this change associated with, there was none attached to the change.
