Test case

If a layer is paginated but has a grandparent that is positioned, paintPaginatedChildLayers crashes due to columnLayers being empty.

Attached is a test html file.  My simple fix was to remove the logic in paintPaginatedChildLayers that checks for curr->parent()->renderer()->isPositioned() similar to updatePagination.
