Using a Spawn Agent spawns an unknown invisible entity

Using a Spawn Agent spawns an entity which cannot be killed. It does not move but it can be pushed by pistons. You cannot place blocks in its position.

Steps to Reproduce:

1. Use the command “/give @s spawn_egg 1 56”.
2. Use the spawn egg anywhere.

Expected Results:
The egg should either not spawn anything or spawn an Agent; however, this is Bedrock Edition, not Education Edition

Observed Results:
The egg spawns an invisible entity without an identifier
