/**
 * Handles the edge case where transforming multi-selection to decisionList results in

 * decisionList to ensure the target type exists.
 *
 * Similar to handleEmptyContainerEdgeCase in wrapMixedContentStep, but specifically for
 * multi-to-decisionList transformations where blockquotes break out.
 *
 * @param result - The current result nodes after processing
 * @param hasCreatedDecisionList - Whether a decisionList was already created during processing
 * @param targetNodeTypeName - The target node type name
 * @param schema - The schema
 * @returns The result nodes with an empty decisionList prepended if needed, or the original result
