Template talk:First Prince Timeline

I've come across the "First Prince Timeline" template transcluded on pages such as Marie Davion (24th c.) and Joseph Davion (27th c.). The template specifies "display:none" and "font-size: 0px", both of which ensure it's not displayed in the articles where it's invoked. Those articles also use the appropriate Succession templates, which is displayed and covers basically the same information.

Does the First Prince Timeline template serve some function that's not obvious? Tosta Dojen (talk) 22:14, 7 September 2020 (EDT)
