Enderman teleport sound only plays at position it teleports to

The Bug

The minecraft:entity.enderman.teleport sound plays at the position the enderman teleports to, which is not the case in 1.8.9, where it also plays at position it teleported from.

Steps to Reproduce

• Place down a bucket of water and obtain some enderman spawn eggs.

• Summon some endermen in the water by using the spawn eggs and listen closely as you do this.

Observed Behavior

The minecraft:entity.enderman.teleport sound ("Enderman teleports") plays at the position the enderman teleports to.

Expected Behavior

The minecraft:entity.enderman.teleport sound would play at the position the enderman teleports from.

Code Analysis

By @unknown using MCP Reborn 1.16.5 mappings

At net.minecraft.entity.monster.EndermanEntity.teleportTo() the game simply only tries to play the sound after the enderman teleports:

if (flag && !flag1) {
         boolean flag2 = this.attemptTeleport(x, y, z, true);
         if (flag2 && !this.isSilent()) {
            this.world.playSound((PlayerEntity)null, this.prevPosX, this.prevPosY, this.prevPosZ, SoundEvents.ENTITY_ENDERMAN_TELEPORT, this.getSoundCategory(), 1.0F, 1.0F);
            this.playSound(SoundEvents.ENTITY_ENDERMAN_TELEPORT, 1.0F, 1.0F);
         }

         return flag2;
      }

Which could be fixed by duplicating the if statement above the teleport attempt as well

if (flag && !flag1) {
         if (!this.isSilent()) {
            this.world.playSound((PlayerEntity)null, this.prevPosX, this.prevPosY, this.prevPosZ, SoundEvents.ENTITY_ENDERMAN_TELEPORT, this.getSoundCategory(), 1.0F, 1.0F);
            this.playSound(SoundEvents.ENTITY_ENDERMAN_TELEPORT, 1.0F, 1.0F);
         }
         boolean flag2 = this.attemptTeleport(x, y, z, true);
         if (flag2 && !this.isSilent()) {
            this.world.playSound((PlayerEntity)null, this.prevPosX, this.prevPosY, this.prevPosZ, SoundEvents.ENTITY_ENDERMAN_TELEPORT, this.getSoundCategory(), 1.0F, 1.0F);
            this.playSound(SoundEvents.ENTITY_ENDERMAN_TELEPORT, 1.0F, 1.0F);
         }

         return flag2;
      }
