MacOS full screen button pauses game

[Alex25820]

Godot version

3.4.stable

System information

macOS Big Sur 11.6

Issue description

When hovering over the full screen button on a game created in Godot the game gets paused. The game also gets paused when pressing the full screen button but for a much shorter period.

This causes problems in my multiplayer game as the players are no longer properly synced. If I hover over the full screen button for a few more seconds (around 10) the client disconnects from the server.

Steps to reproduce

1. Create a project that has a moving element.
2. Export the project and run it on macOS.
3. Hover over the full screen button.
4. The game is now paused.
