tetektoza 4dcef14bd8 Gui: Prevent whole-object highlight when picked list is enabled
Removed the logic that forced `onTop=1` when `needPickedList()` is true
in View3DInventorSelection. This was causing the entire object to be
highlighted instead of just the selected sub-element when the "Picked
object list" option was enabled.
