Description:
When you press F11 it goes into fullscreen, and if you press it again it comes out of full screen. However when It comes out of full screen you cannot resize the window. This does not occur in full versions before 1.8.2.

What I expected to happen was:

I would be able to resize the window normally after exiting fullscreen with F11.

What actually happened was:

The screen size was not editable with the dragging function or the maximize button.

Steps to reproduce:

1. Launch minecraft after version 1.8.2-pre5
2. In the Main menu screen, press F11
3. Press F11 Again
4. Notice you cannot resize the minecraft window by dragging the edges or pressing the maximize button
