While testing this, I discovered that promoting followups in general is broken in 10.0.18 now. This seems to be because of #18611 since it now skips handling the "_promoted_fup_id" parameter when there is saved input, which will always be the case since "_promoted_fup_id" itself exists in the saved input.
