在使用Fluent UI组件时，我在react js中收到此警告。我做了很多尝试，但无法删除此警告。有人有主意吗？

代码

<Dialog        
        as="div"
        classname="PopupDialogs"
        open={showPopUp}
        styles={{ justifySelf: "unset" }}
        header={GetSubject()}
        content={<Flex>{displayTime}</Flex>}
        footer={footer()}
        onCancel={() => { OnClosePopUp(false) }}
        onconfirm={() => { }}
        headeraction={context.userProfileData.isTeacher && headeraction()}
    />
