/**
 * `rc-cascader` is much like `bonree-tree-select` but API is very different.
 * It's caused that component developer is not same person
 * and we do not rice the API naming standard at that time.
 *
 * To avoid breaking change, wrap the `bonree-tree-select` to compatible with `rc-cascader` API.
 * This should be better to merge to same API like `bonree-tree-select` or `bonree-select` in next major version.
 *
 * Update:
 * - dropdown class change to `rc-cascader-dropdown`
 * - direction rtl keyboard
 *
 * Deprecated:
 * - popupVisible
 * - hidePopupOnSelect
 *
 * Removed:
 * - builtinPlacements: Handle by select
