// we insert blocks via `insertSideChain`, we only commit `td`, `header`
// and `body` if it's non-existent. Since we don't have receipts without
// reexecution, so nothing to commit. But if the sidechain will be adpoted
// as the canonical chain eventually, it needs to be reexecuted for missing
// state, but if it's this special case here(skip reexecution) we will lose
// the empty receipt entry.
