[PATCH] Fix Scroll Wheel issue in AllApps submenu of Application Dashboard

Scroll with mouse wheel was problematic in AllApps subsection. It worked
partially, abruptly stopping when hovering over app icons, or just
during mouse wheel scrolling.

The problem is that QQuick WheelInterceptor::findwheelArea() never entered
into its if statement because there are 3 children elements of QML parent,
and their z axis values are 1, 0, 0 respectfully.

BUG: 486481
FIXED-IN: 6.4.0
