Subject: [PATCH] Bugzilla #37468: Bugfix: A normal break inside a table
 resulted in the next part to be sent to the next page instead of the next
 flow. TableContentLayoutManager produces KnuthPenalties with breakClass=0.

+    <p>
+      This test checks multi-column documents. Checks a problem described in Bugzilla #37468.
+      A table that was broken in multiple parts started a new page after each break possibility
+      instead of changing to the next flow area.
