Game client no longer allows OS X full screen

Pressing F11/fn+F11 is a pain and the game's built-in Fullscreen option is different and un-tabbable compared to before. The new launcher is still "fullscreenable" like the last launcher but the game client is no longer.

Ways to fix this problem:

– Restore the game client's OS X full screen feature again somehow
– Make the game's options full screen feature be treated as a space (tabbable alone isn't good enough—it was a space before, so why not now?)

In the top right corner, one may see that the launcher can still go full screen:

In this screenshot, the game client does not have the fullscreen button, making it very annoying to quickly play the game.

How to reproduce:

• Start OS X
• Launch new Minecraft launcher
• Login with any Minecraft version ever
• Click top right corner of game window
  If game doesn't go fullscreen, you have reproduced the bug.
