Mouse Cursor goes to second monitor when unpaused

when playing with my friends i noticed i would interact with a discord window and it almost made me leave a server,I looked into it and noticed when i looked right my mouse would go to my second monitor when unpaused

Steps to replicate

-Have 2 Monitors,Have the game either or in fullscreen or windowed

-Go into a Minecraft world

-Look to the right in a circle,If this is a bug your mouse will appear on your second monitor.
