Example:

             <Header>
                <Header.Item>
                     // Rule does not detect the fontSize
                    <Header.Link href="#" fontSize={2}>
                        // Rule detects the mr
                        <StyledOcticon icon={MarkGithubIcon} size={32} mr={2} />
                        <span>GitHub</span>
                    </Header.Link>
                </Header.Item>
            </Header>
