Skip link on 22 app routes moves focus to the panel but leaves the URL unchanged

A keyboard-focus test of 22 app pages on the OnePassApps site checked the Skip to content link, which targets a main element with id main on every route. Pressing it with Enter moved focus to that main element on all routes, but the URL fragment stayed empty and the page did not scroll. The link is never the first Tab stop, since at least three shell controls come before it, and after it the shell's own controls still precede the app's first field. The first app control arrives as the 10th or 11th stop on most routes, and the author declined to give counts for two routes where the fields' accessible names came from wrapping labels.
