They're looking into the icon browser issue. Also, they posted this:
"We will be making an S2 commenting style that mimics the display of the original/previous S1 commenting pages. This new style will retain the ability to use/display comment subject lines. It will also not have the display issue that arises for long threads in the current S2 customized comment pages, where long threads are very 'squished' (a few words per line, etc) -- threads will display as they did in the previous commenting scheme. We are aiming to have this available within a few weeks."
Not sure if that will help you, but it means I can go back to my original style if I wish. But I kind of like the changes, aside from the smaller font. So I might just keep it as it is now.
