/**
 * Returns an array of layers sorted such that parents appear before their children.
 *
 * **Why**:
 * - mount order for parent-child relationships is unstable due to portals
 * - event handling relies on parents being before children in the array
 *
 * This function ensures that for any parent-child relationship, the parent layer
 * will always appear before its child layer in the returned array,
 * resulting in consistent behavior.
 *
 * @param layers - A set of DismissableLayerElements to be sorted.
 * @param branchedLayers - A map where each key is a parent layer and its value is a set of child layers.
 * @returns An array of DismissableLayerElements sorted by parent-child relationships.
