"Back" button in "Online play is not rated" pop-up doesn't send the player back to the menu when joining a Realm with "Screen Animations" disabled

Summary:
When joining a Realm, the "Online play is not rated" pop-up appears. When clicking on the "Back" button for the first time since launching the game, the game takes the player back to the main menu as expected. However, after that, the player always joins the Realm. This only happens when "Screen Animations" is disabled.

This doesn't affect singleplayer worlds with the "Multiplayer Game" toggle enabled or servers.

Steps to Reproduce:

1. Navigate to Settings > Video and disable "Screen Animations"
2. Join a Realm
3. When the "Online play is not rated" pop-up appears, click on the "Back" button
4. Join the Realm again
5. When the "Online play is not rated" pop-up appears, click on the "Back" button again

Observed Results:
The player joins the Realm.

Expected Results:
The game takes the player back to the main menu.
