Bug 977056 - [Dialer] Visual discrepancies: Call ended view under conference call participants list

In the future, I don't think we should take the effort to document every private function. I'm happy that you did this here, but I don't want it to turn into an unspoken rule. The reason being that I don't want to discourage people from breaking up code into more functions because then they'll have to comment it more heavily. What do you think?
