In Safari on iOS you can use the back button of the browser to jump back to where you were on the page before you clicked the link to the reference. You should see if the browser you are using does that as well.
Absolutely :) Named anchors in a page have been around for a long time and I recall that going back from a page internal link would bring you to the place in the page that you were for as long as I can remember.
Would be interesting to know which browser was the first to keep track of scroll position for history entries.
Mosaic was before my time but I wouldn’t be completely surprised to learn that even it would store scroll position.
