Camera fade effects still plays when the game is paused

When you apply a fade effect to your camera using /camera commands, and then pause the game, it does not stop the fade effect and proceed to fades in and out the camera.

Steps to reproduce:

1. Run: /camera @s fade time 3 2 3
2. Pause your game

Expected results:
The fade effect will stop, and will resume when you unpaused the game.

Observed results:
The fade effect does not stop, despite the game is being paused.
