The bug

Using F11 to go into full-screen causes the Minecraft window to minimize to the Dock whenever cmd-tab is pressed to "tab out" another window. The behavior works correctly when Minecraft is maximized using the green window maximize button.

How to reproduce

1. Launch the game
2. Press fn-ctrl-F11 (to switch into full-screen, if not already)
3. Press cmd-Tab (to tab out to another application)
4. Press cmd-Tab again to switch back to Minecraft

Observed behavior: Window minimizes to Dock, making it impossible to tab back to, and forcing the user to click the minimized window to bring it back. (Demonstrated in attached video)

Expected behaviour: Minecraft should remain maximized but allow you to tab out and back in again, just as it does when you maximize the window using the green window "Maximize" button.
