Problem:
Tridents and possibly other entities similar to this one disappear if you move away from them depending on the simulation distance and the rendering distance.

Tests:
-Test 1
To replicate it with the tests I did, put the settings like this:

• always render distance at 8 chunks

Simulation distance:
in the first test at 4 chunks

Results:
If you go 13 chunks away from the trident in a straight line, and you stay in the last block of this chunk, when you return, it will still be when you return, but when you enter chunk 14 it will disappear.

(in the test I did I put tridents in the Z coordinate: -1 in the last block outside a chunk and I moved away the 13 chunks and I was in the last block of chunk 13 (Z coordinate: 207) and when I returned, the trident it was still there, and when I went to the block at coordinate Z: 208, that is to chunk 14, the trident disappeared).

• • • In test 2, at 6 chunks of simulation distance, and in test 3, at 8 chunks of simulation distance and both at 8 chunks of rendering distance were the same results as in the first test at 4 chunks of simulation distance.*

Test 4
To replicate it with the tests that I did put the settings like this:

• always render distance at 8 chunks

Simulation distance:
in the fourth test at 10 chunks

Results:
If you move 15 chunks away from the trident in a straight line, and you stay in the last block of this chunk, when you return, it will still be where you left it, but when you enter chunk 16 it will disappear.
(In this test I put tridents in the coordinate Z: -1 in the last block of the chunk and I moved away the 15 chunks and I was in the last block of chunk 15 (coordinate Z: 239) and when I returned the trident was still where I left it , and when passing to the block at coordinate Z: 240, that is, to chunk 16, the trident disappeared).

Test 5
To replicate it with the tests that I did put the settings like this:

• always render distance at 8 chunks

Simulation distance:
in the fifth test at 12 chunks

Results:
If you move 17 chunks away from the trident in a straight line, and you stay in the last block of this chunk, when you return, it will still be where you left it, but when you enter chunk 18 it will disappear

(In this test I put tridents in the coordinate Z: -1 in the last block of the chunk and I moved away the 17 chunks and I was in the last block of chunk 17 (coordinate Z: 271) and when I returned the trident was still where I left it and when moving to the block at coordinate Z: 272, that is, to chunk 18, the trident disappeared).
