Nesting a :class:`.FlowController` inside another in a :class:`.PassManager`
could previously cause some transpiler passes to become "forgotten" during
transpilation, if the passes returned a new :class:`.DAGCircuit` rather than
mutating their input. Nested :class:`.FlowController`\ s will now affect
the transpilation correctly.
