misalignment

Hi,
I’m using Side Matter and it’s perfect. Except for this one post, all my notes are so well behaved. For this post, which is really long, the notes are misaligned starting from the second one. The first one show up fine, but the second is down from where it’s supposed to be by several paragraphs, and vice versa with the third and fourth,… To the point that the sidebar is much, much longer than the post itself now.

Do you know of anything possible problems that might be causing this? The theme I’m using is Underscores with modifications by me and there’s no CSS conflicts that I could find.

Thanks so much and great work!
