This patch removes the check for a footer node,
intoduced by
23f698ec
preserving the behaviour for the connected bug reports
i13832 and i24135.

Without this check, the wraping becomes enabled for footer
objects, too.

With this enhencement, the commits
7df33caa
d3db6ff4
are directly affected and therefore the unit test is edited.
