After inserting a page break, if the new page starts with a heading line then
the heading format runs into the previous page last line. This is especially
problematic when the heading format includes shading because the last line of
the previous page becomes completely shaded.

If I try to remove the heading format from the previous page, then the
heading line of the new page disappears!

This also happens with columns: the heading of a new column line runs into
the old one when using the column break.
