Dedicated server operators can make all monsters despawning unintentionally with the world options screen

Steps to reproduce:

1. Be on a dedicated server with operator permissions

2. Summon a monster that despawns on peaceful (for example a husk) in front of you

3. Go to the world options screen and click on the difficulty button serveral times

Expected result:

The difficulty not instandly changes when clicking on the difficulty button.

Actual result:

The difficulty instandly changes when clicking on the difficulty button. This makes the husk/mob in front of you (and all other monsters) despawn instandly once you reach “peaceful” on the difficulty button.

This behavior can lead to all monsters on the server despawning unintentionally when a server operator changes the difficulty (also named monsters or monsters riding boats etc.)
