Bring comments into a scrollable section

Some articles, like the old "var," may not be very attractive to read. We just know that 'var' should not be used, rather than reading a lot about it. However, one may intend to read it, especially when an interview is coming up.

Jumping into the article for the first time can feel overwhelming; it appears to be a long read because of the lengthy scrollbar.


But actually it ends half way and the rest half of it are just comments.


The feature request is to place the comments in a scrollable section so that the page's scrollbar accurately reflects the length of the article.

先檢查文章頁面的版面配置和留言呈現，然後重現舊版 "var" 文章中的長捲軸。完成的條件是留言佔據自己的可捲動區段，而頁面捲軸反映文章內容，而不是完整的留言清單。
