Mouse cursor isn't locked to the window for Minecraft

When multiple monitors are available and you move your cursor around, it is not locked to the window as it should be, you still move the player around but the cursor will be visible on the second monitor and if you were to click to interact with something in game, it would focus to that monitor. (its a bit hard to record something like this but I can try to do this, it would be best to test this yourself with multiple monitors)
