When saving a doc and regenerating the breadcrumbs array, a phantom row will append itself to the end of the array on save. This is because of fixes made in #13551 changed the way we merge array and block rows from the server.
To fix this we need to ensure that row IDs are consistent across form state invocations, i.e. the hooks that mutate the array rows cannot discard the row IDs.
