Automatically expand footnote when referenced in URL hash fragment

[inwardmovement]

Can you add a feature to update the URL when we click on a footnote reference, just as footnotes links does (#fn:1) ? So we can deeplink to the footnote/popover.

Been giving this some thought and it's not as straighforward as it seems, especially since littlefoot allows you to activate multiple popovers concurrently as well as opening them on hover. I feel like this is a feature best left to individual developers to implement through activateCallback and not built into the library:

littlefoot({
  activateCallback: (popover) => {
    window.location.hash = '#' + popover.id
  }
})

It probably still makes sense to automatically expand a popover if its ID is referenced in the fragment when you open the page so I'll keep the issue open for that.
