As $form_state is the global state, I'd rather repeat this in each element or pass it as a separate argument.

Seems like we're missing a bit of context in that function anyway, maybe pass in $key and $parent_key explicitly as new arguments and and just recalculate the id there? Maybe provide a helper function.

Re-upload of the interdiff, I think that's the patch that we want here :)

Committed and pushed. Opened #2032263: Add tests for review/reject form interations.
