Profiler graph renders above all other layers

When pressing SHIFT + F3 to bring up the profiler graph it renders above other layers of the minecraft window when the windows is small.

Screenshot 1 (mcrndr1): profiler graph is above the pause menu (this is the problem)
Screenshot 2 (mcrndr2): profiler graph is above the default debug screen (this isn't a problem)

(Not sure if bug or WAI)
