fdo#59573 position after fieldmark and before annotation anchor is read-only

Also revert "SwTxtPaintInfo::_DrawBackBrush: draw dark border around
comment highlight" (commit 57c8c34f), as
it draws confusing vertical lines inside the comment when it has
multiple runs.

(cherry picked from commit bd505fdb)
