A hyperlinked TOC wrote each entry's page number as plain text inside the
link. Word writes it as a PAGEREF _Toc… \h field, so Update Field in Word
moves the number with its heading; with plain text the numbers stay what
they were when the file was saved.
Entries that link to a bookmark now end with that field (result: the page
number). Entries without a link and \n levels are unchanged. The DOCX span
test looks for the TOC's own end, the last one, since PAGEREF fields now end
inside it.
