- [Major] Changed `hash` passed to `querySelector` to `decodeURIComponent(hash)` to fix the issue where non-English anchors were not correctly positioning the popover content to the corresponding title. - [Minor] Updated the type hint from `HTMLLinkElement` to `HTMLAnchorElement` as the passed element is an `<a>` element, not a `<link>` element (reference: https://developer.mozilla.org/en-US/docs/Web/API/HTMLLinkElement).
