Fix positioning and placement of initially invisible items in layouts
Instead of misusing implicitWidth/Height as a storage mechanism in
scenarios where width/height is used for preferred size evaluation,
new members are created to hold this information to prevent incorrect
sizing in mentioned scenario and get rid of blocking signals.
