Code review comment for lp:~unity-team/unity8/lp1475678.surface-occlude

This qml state fast-forwarding is a real PITA. This is what happens when I maximize the settings application:

So we do generate some noise, with apps getting switched unnecessarily (invisible-then-visible-then-invisible).

But not a deal-breaker. Guess we can optimize (or work around) that later.
