There are no need to scroll this modal. In fact, error comes from this condition. After modal will be closed it should reset scrolling state as I think:

  handleClose = (e) => {
    debug('close()')

    const { onClose } = this.props
    if (onClose) onClose(e, this.props)

-    this.trySetState({ open: false })
+    this.trySetState({ open: false }, { scrolling: undefined })
  }
