- Fixed a bug involving the new flattened JOIN structures which
are used with :func:`.joinedload()` (thereby causing a regression
in joined eager loading) as well as :func:`.aliased`
in conjunction with the ``flat=True`` flag and joined-table inheritance;
basically multiple joins across a "parent JOIN sub" entity using different
paths to get to a target class wouldn't form the correct ON conditions.
An adjustment / simplification made in the mechanics of figuring
out the "left side" of the join in the case of an aliased, joined-inh
class repairs the issue. [ticket:2908]
