We should add some visual style to communicate to the user they have to jump to a specific section on the tab

This is great, thank you! I know you mentioned the need for a visual style when using a skip link but this is not necessary in this case as we are not using the link to skip to something focusable/interactive. The next tab stop will again show the focus indicator as expected.
