The bug
Zombies of a village siege spawn more likely in negative X and Z direction. This is probably difficult or impossible to notice in-game but can be seen when looking at the code.
Code analysis
Based on 1.11.2 decompiled using MCP 9.35 rc1
The method net.minecraft.village.VillageSiege.findRandomSpawnPos(BlockPos) uses nextInt(16) - 8 as horizontal offset and nextInt(6) - 3 as vertical offset. The problem is that this produces numbers from -8 to 7 (both inclusive) respectively -3 to 2 (both inclusive).

Seems to still be the case in 22w18a, at least partially (only for the horizontal offset).

Is this still a issue in the latest version of the game(currently 1.13.1)?
If so, please add it to the affected versions, thanks!
