The mouse cursor does not properly switch focus to the game window if you switch to another window using Alt+Tab while joining the world

What is the essence of this bug: If you start joining the world and switch to another window using the Alt+Tab key combination and then switch to the game window in the same way, the mouse cursor in the game itself will be visible, which should not be. You can move, etc., i.e. the visible cursor in the game will not interfere with you. In order to reproduce this, you need to:

• Disable auto-pause when you lose focus using the F3+P key combination. (this is important!)

• Start joining the world.

• Then quickly switch to another window using the Alt+Tab key combination. (you have to do this before entering the world!)

• Wait for 10 seconds and then switch to the game window in the same way.

• The mouse cursor will not properly switch focus to the game window, i.e. it will be visible in the game itself, but the cursor itself will not interfere with your movement.

• The problem is solved by opening and closing the chat pause menu or by simply clicking the mouse.
