unity dash and top bar shown while using compiz enhanced zoom desktop

when i zoom-in using Compiz's Enhanced Zoom Desktop - i use it to navigate and manage the desktop while being zoomed-in.

however, when using Unity (unlike Gnome-Classic) - the dash icons and top bar aren't hidden (again, unlike gnome classic).

beyond the fact it's an aesthetically annoying issue - it's also a bug - due to the fact i can't click the indicator applications nor the global menu.

Compiz within Unity should behave like it does in Gnome Classic - blend in when i zoom in so i can click in any place around the desktop.

cheers.
