Bookmark list broken on story page

[slowhandduke]

For some reason the bookmarks list shown when clicking the icon on a story page is no longer sorted alphabetically. Instead I get a seemingly random set of my reading lists at the top of the list, and then the rest are sorted correctly.

Looking at the bookmarks from a tag list or from then reading list shows then correctly ordered.

For instance, in TagListBookmarks.png they are ordered, but in StoryPageBookmarks they are in the wrong order.
