Load functions are executed after the player joins

When we join a map that there is Datapacks with the load functions with a tellraw command executed by #minecraft:load, we recieve the load messages.
It’s same for other commands, not only tellraw, but it’s an example to know if the load function is executed after ou before you joined.

I didn’t see this change in changelogs, so I think it’s a bug because the load functions are supposed to be executed before the player joined.

Steps to reproduce :

1. Download the Test Load Function Datapack of medias (or any Datapack with a load function that execute a tellraw command)

2. Put the Datapack in a world

3. Join the world

4. Look at the chat

Observed result :

After you joined the world, you recieved in the chat the message that says the Datapack is loaded. Because the load function as been executed after you joined the world, so you can see the message.

Expected result :

After you join the world, you don’t receive any message in the chat that saying the Datapack is loaded. Because, the load function as been executed before you joined the world, so you can’t see the message.
