of the previous paragraph(s), as in editing without change tracking.

This is a workaround for the regression introduced by #i100466#.

NOTE: We change the style of the first removed paragraph to restore
normal editing function during change tracking, too. Manual fix
of the spoiled paragraph does the same style changes in the
previously deleted paragraphs, so this commit doesn't introduce
any new oddity.
