When a comment is added to a text at the bottom of a page, and then people are replying to this comment (let says we have 10 replies to this comment), the comment appear collapsed. This is correct.
Now when we expand the comments, there is a bug where the vertical scroll bar does not change so we cannot read all the comments (only the top 2 or 3 comments will be shown, the others are hidden by the bottom of the page, and the scroll bar do not expand to be able to reach them).
The only workaround I have found is to copy the link of the last comment and open a new brower tab with this link to be able to read all the comments.
It would be better to add a scroll bar to expanded comments to be able to read them in any case.
EDIT - Example of a list of comments at the botom of a page, the scroll bar is at the end of the page but more comments cannot be shown...
