>
> When wrapping a DoFn in DoFns.detach(), the context does not get passed down
> to the enclosing DoFn when setContext is invoked, meaning counter
> incrementing and other features which rely on the context being available
> don't work as expected. This needs to be patched to make setContext change
> the context of both the wrapper and the delegate DoFn.
