From 8212dfcf14c63c006b9e1c37595f3d62eab052cf Mon Sep 17 00:00:00 2001
From: "Mark J. Titorenko" <mark@titorenko.net>

Subject: Do nothing when the same block is included again.
If the same block is included multiple times, we no longer raise an exception
or overwrite the included block instance variable.
Fixes #14802.
