Is there a way to focus a popover for a Safari extension?

Just wanted to know if anyone knew how to put the focus on a popover for a Safari extension. Currently, the popover acts as if the window is inactive. This prevents any mouseover e开发者_Go百科vents from working and trying to type in any input field is difficult because there is no flashing cursor.

According to a post on the Safari developer forums, this is a known issue with Lion and they are looking into it.
