using Select inside <form /> with onChange

I use tag <form/> with onChange for observing the changes from form fields. Native <select /> tag works correctly, but changes inside Select from react-select don't trigger onChange.

<form onChange={handleChange}>
      <input />
      <select type="select">
        <option value="123">123</option>
        <option value="321">321</option>
      </select>
      <Select
        className="basic-single"
        classNamePrefix="select"
        name="color"
        options={colourOptions}
      />
</form>

Start by reproducing the behavior in the linked CodeSandbox, comparing the native select with react-select inside a form using onChange. Trace the Select event handling from the example and identify the relevant project entry point; the issue is done when changes from Select reliably reach the form's onChange handler.
