Clicking Top Level comments only takes you back to the first page of comments. This is very annoying.

I got through three pages of comments on top level only then replied to one. This brought up all the comments (so I could see mine), so I clicked on top-level only again, and was back at page one instead of the one the page I was on. When I clicked top level only after I had replied directly to the post, the same thing happened.

This looks like it's only a problem when I've commented (and therefore when the URL i'm on doesn't include the comment page number).
