Drawing objects inside text boxes are supported by Writer, but not by
Word. Such a document model is still created by the DOCX import for
floating tables.  Till we recognize floating tables on export, at least
make sure that inline shapes are delayed till the end of the floating
table to avoid invalid output.

That matches the behavior of handling anchored shapes inside shape text.
