Accessibility issue due to ARIA

[hirakch]

We are getting accessibility issue due to ARIA properties in single select field. Here is the report

Configuration:

<TreeSelect style={{width: '100%'}} transitionName="rc-tree-select-dropdown-slide-up" choiceTransitionName="rc-tree-select-selection__choice-zoom" dropdownStyle={{maxHeight: 350, overflow: 'auto'}} placeholder={t('Category')} searchPlaceholder={t("Search")} showSearch allowClear treeLine labelInValue value={selectedCategory} treeData={treeCategoryList} treeNodeFilterProp="title" filterTreeNode={true} onChange={this.categoryOnSelect} />

The PR might have worked in previous version: https://github.com/react-component/tree-select/pull/112 not in the current version
