If you cmd+tab to a window that has its own full screen space, you can see that the window does not active, and that hitting a keyboard shortcut that is intended to be valid just gives you a beep. You have to manually click in the window to activate it. This especially affects Safari in full screen windows with video, where hitting space to pause or left/right to scan is no longer effective.
