This is required when more entries with the same name don't fit into the
fragment. With the existing means for fragment offset specification such a splitting to be
prohibited.

(cherry picked from commit 24955e6)
issue.

Snapdiff listing fragments have different boundaries in Reef and Squid+
releases hence original reproducer (made for Reef) doesn't work properly
in S+ releases. This patch fixes that at cost of longer execution.
This might be redundant/senseless when backporting to Reef.
