Focus is lost for users tabbing through a page with the the "summarize" plugin

I'm using the "summarize" and "expander" plugins but have noticed that the tab order is reset (goes back to the top of the page) whenever I expand or collapse a section, causing a user to have to retab through the enitre page. Is there a way to have the focus go to the next link on expand and collapse?
