I've just upgraded to 5.x line from 4.x, and couldn't find a way to pass onRenderCaret prop from Combobox to InputPopup.

I've fixed it with

const { onRenderCaret, onRenderPopup, inputPopupProps, styling, ...restProps } = this.props;
const _onRenderCaret = inputPopupProps.onRenderCaret ? inputPopupProps.onRenderCaret : onRenderCaret;

//

{_onRenderCaret(styling, isActive, hover, caret)}

in render method of InputPopup, but not sure this matches the coding style of the project.

Am I missing something, or is it really missing?
