/**
* 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`
