/**
 * To match accessibility requirement, we always provide an input in the component.
 * Other element will not set `tabIndex` to avoid `onBlur` sequence problem.
 * For focused select, we set `aria-live="polite"` to update the accessibility content.
 *
 * ref:
 * - keyboard: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/listbox_role#Keyboard_interactions
 *
 * New api:
 * - listHeight
 * - listItemHeight
 * - component
 *
 * Remove deprecated api:
 * - multiple
 * - tags
 * - combobox
 * - firstActiveValue
 * - dropdownMenuStyle
 * - openClassName (Not list in api)
 *
 * Update:
 * - `backfill` only support `combobox` mode
 * - `combobox` mode not support `labelInValue` since it's meaningless
 * - `getInputElement` only support `combobox` mode
 * - `onChange` return OptionData instead of ReactNode
 * - `filterOption` `onChange` `onSelect` accept OptionData instead of ReactNode
 * - `combobox` mode trigger `onChange` will get `undefined` if no `value` match in Option
 * - `combobox` mode not support `optionLabelProp`
