Long comments circumvent downvotes

Since the Trac link seems to be down (assuming that link's correct), there's a problem of comments that force horizontal scroll also block the Vote Up / Vote Down options (as well as the others).

Ex: post #388163

As do short ones.

I see the vote up/down options fine.

I'm using Opera, and haven't checked if this occurs in IE or FF.

It shows up fine in both IE and FF. Can't check chrome but I imagine it's not an issue there either.
