Jiingy, I have tried to reproduce the issue in 1.21 based on what I remember when I encountered this issue back in 1.16.3 and could not. I recommend closing/resolving the issue report.
Steps I tried to reproduce issue:
clear a perimeter beyond render distance in nether using fill commands (in 1.16.3 I had cleared a large amount as I wanted to make a skyblock style world)
place 5x5 platform of magma blocks at y0 (I believe in 1.16 only zombified piglin (ZP) could spawn on magma blocks, during my attempt to reproduce issue in 1.21 I had to add a slab roof to stop magma cubes)
place bridge going far enough away to allow spawning. first 2 blocks of bridge should be open trapdoors to drop ZP into void
move away till ZP spawn, make sure to be in survival for next steps
move back towards platform, hit one of the ZP.
expected behavior: all ZP aggro, chase player, fall into void.
current behavior: expected
issue behavior from 1.16.3: ZP that got hit aggros and chases player. No other ZP aggro.
while I did not test too extensively this time, I remember in 1.16.3 the issue occurred very commonly as I was working on making a ZP farm and would frequently clear the platform to make building easier by hitting a ZP so they would all run off the edge into the void. Again, recommend just closing/resolving this issue report.
