Glow ink being picked up by zombies causes lag buildup

Due to the new way Glowsquids now spawn in caves its causing issues where spawned zombies pick up the ink sacs and are therefore not despawning. I came across a cave that had around 50 zombies each holding an ink sac. Unfortunately i had to kill them all due to some lag it was causing so no screenshot of that situation but i found more today. This is on a snapshot server ive been running since 1.16 snapshots. Its Java 16 etc etc
