> The "unique ref" ids used in PipelineContext are generated on the fly, which
> can cause us to get a different id for the same component in different
> contexts.
> This becomes a problem when ExternalTransform is used, because it creates its
> own pipeline context for expansion. So its possible the component ids in the
> expansion request will actually refer to an entirely different component when
> the pipeline is finally assembled for execution.
