- Fixed a bug where clause adaption as applied to a :class:`.Label`
object would fail to accommodate the labeled SQL expression
in all cases, such that any SQL operation that made use of
:meth:`.Label.self_group` would use the original unadapted
expression. One effect of this would be that an ORM :func:`.aliased`
construct would not fully accommodate attributes mapped by
:obj:`.column_property`, such that the un-aliased table could
leak out when the property were used in some kinds of SQL
comparisons.
fixes #3445
