So we devirtualize to StartDisplay but that leads to linker failure because
StartDisplayingFrame is not linked with the object file.
I think this is similar to some earlier testcases we run across in libreoffice
and we managed to declare it invalid - if you provide inline function body you
need to link the unit with symbols it uses.
