[Bug]: URI Text Fragments do not work with "Deep Dive" text blocks

Summary

Clicking a doc link that includes a Text Fragment does not scroll nor highlight the relevant text, if that text happens to be inside a "Deep Dive" section.

Details

When attempting to quote a part of the doc that is under a "Deep Dive" section, with a URI text fragment: clicking the link will open the documentation page in the browser, but without scrolling to the relevant block nor highlighting the quoted part of the documentation.

However, there are two cases the highlighting works. Both of those require the page to already be loaded, the fragment is added to the uri of the page:

• If the section is not opened beforehand: the browser still does not scrolls to the section nor open it, but the text is correctly highlighted.
• If the section is opened beforehand: the browser scrolls to the section and highlights the text as expected

Here's a video capture of the problem:

リンク先の react.dev/reference/react/useCallback ページから始め、初回ナビゲーション時に「Deep Dive」セクションがどのようにレンダリングされ、開かれるかを調べます。新しいページの読み込みで指定されたテキストフラグメント URL を再現し、その後、セクションを読み込んで開いた後にフラグメントを追加した場合と比較します。直接ナビゲーションしたときに、ブラウザーが折りたたまれた「Deep Dive」セクション内のテキストまでスクロールし、そのテキストをハイライトすれば完了です。
