Fixes broken item-lookup for untransformable items.

Found during manual testing (manualtests/graphicsview/untransformable).
At some point it was not possible to click on an untransformable item.
The problem was that none of the untransformable items were top-levels,
and none of the transformable top-level items were in the same area,
resulting in an empty list of estimated top-level items.

Auto-test included.
