Bug Description

If we use blur in a element inside a cloned group or directly cloned, this will not be visible in clones on the exported PDF.
(See the attached image with screenshots. Also the Inkscape PDF importer do not see this elements!)

Clones with blur from a non blured element are ok!

I discover this problem in a real-world art service.

The problem seems to appear for clones of elements with any
filter, not only blured elements.

I looked into the problem a found the following:

sp_generate_internal_bitmap (pixbuf-ops.cpp) is called from
sp_asbitmap_render (cairo-renderer.cpp) for both the original
element as well as the cloned element. However, in the second
case the created bitmap is empty. So it seems that
sp_generate_internal_bitmap does not work for cloned elements.

The attached patch fixes the issue. The cloned object was hidden in the function hide_other_items_recursively.
The same function exists also src/helper/png-write.cpp, but I don't know, if the same fix should applied there.
