Can we locate the line number when react makes a warning like this "Unknown DOM property class. Did you mean className?"

There is no hint about which code made this warning.

HTML in props.dangerouslySetInnerHTML,
      '`props.dangerouslySetInnerHTML` must be in the form `{__html: ...}`. ' +
      'Please visit https://fb.me/react-invariant-dangerously-set-inner-html ' +
      'for more information.'
    );
  }

    warning(
      props.innerHTML == null,
      'Directly setting property `innerHTML` is not permitted. ' +
      'For more information, lookup documentation on `dangerouslySetInnerHTML`.'
    );
    warning(
      props.suppressContentEditableWarning ||
      !props.contentEditable ||
      props.children == null,
      'A component is `contentEditable` and contains `children` managed by ' +
      'React. It is now your responsibility to guarantee that none of ' +
      'those nodes are unexpectedly modified or duplicated. This is ' +
      'probably not intentional.'
    );
    warning(
      props.onFocusIn == null &&
      props.onFocusOut == null,
      'React uses onFocus and onBlur instead of onFocusIn and onFocusOut. ' +
      'All React events are normalized to bubble, so onFocusIn and onFocusOut ' +
      'are not needed/supported by React.'
