Visually, this unit test round-trips terribly.
During round-tripping, the 3 columns (related to textsections)
in the very first section get transferred into the pagedesc. Thus the
first section is "lost". For some unknown reason, another section
is added later on. So, cummulatively, the section count remained
the same, but whatever fixes these two situations will also affect
the section count.

However, it should work fine as an import only test.  There ARE
three sections in MSWord after all.
