forum-mso-en-16671.docx: example document
MS Word generally doesn't like complex content inside of a plainText content
control. Although bug 165359 shows us that it IS possible to have graphics and
shapes inside a plainText control, under some circumstances it can be reported
as corrupt (where it is not corrupt if the control has the <w:text/> marker
removed).
Steps to reproduce:
-open forum-mso-en-16671.docx in LO and resave it.
-open the resaved file in Microsoft Word (file reported as broken)
I bisected this back to 7.6 commit c804c5354855188b5a37219cfe11dc079dc235f4

However, his commit just restored the missing SdtPr values (including the
w:text), so it just exposed an existing weakness.
In this case, the floating graphics are anchored at the start of the paragraph.
Normally the code writes the graphics first (1), in a separate run. But in this
case, because this is all in a floating table, that code path was not followed,
and the SDT was started before the graphics were written out.
