If you have two headers on a page with the same name, you cannot link to any of them but the first with URL#headername syntax. When more than one header has the same name, increment the anchor name tag like #headername #headername-2 #headername-3 and so on, and make a title tag for the header with the anchor name inside it, so we can just hover over the header to see its anchor name.
Duplicate anchors have been numbered for a couple of years.
