Is the problem that it's cutting off the list? It's done with a simple title= attribute on the table row, so I think we're at the mercy of how an individual browser handles that. Firefox on my Mac makes the hover text as wide as the window, but still cuts off for heavily-traveled routes.
We could use some a custom hover text mechanism like HDX does, if there's a preference to do that.
Or maybe it's something else you're seeing?
