Ok, I'm making a brand new world and went to change the world gamerules, but for gamerules with values, I can't change the values before making the world which lead to having to change it after the world was created

Affected gamerules:

Max entity cramming; random tick speed rate; sleep %; respawn location radius; command chain size limit

How to reproduce:

1: create a world

2: go to "more world options"

3: go to such a gamerule listed

4: click on the value

Notice that the typing thing doesn't flash and you cannot change the value

Expected results:
You can change the value of the affected gamerules

Observed results:
You CAN'T change the value of the affected gamerules, meaning you have to change it after the world was created
