groff_ms: table in indented paragraph and page break

Hi,

I was preparing a document that consists of indented paragraphs and one
of those has a table in it.

I was producing a PDF document and needed a page break after that table
but the .bp request dind't produce a page break.

I could fix this by putting the table inside a keep but wonder if this
is expected behavior.  I will attach an example, the command that I use
to produce the PDF is:

$ preconv groff-ms-table.ms | \
  groff -t -Tpdf -P-pa4 -ms -mde > groff-ms-table.pdf

Best regards,

Dirk
