If I visit https://docs.spring.io/spring-boot/docs/2.4.0/reference/htmlsingle/ and hover over sections, the anchors links are not visible. If I visit https://docs.spring.io/spring-boot/docs/2.2.x/reference/htmlsingle/ and hover over sections the anchor link is visible and can be used to copy a link.
