    roomList: Allow right-clicks to trigger header popover
    
    Unlike rows, where we distinguish between primary (activating the room) and
    secondary action (showing the context popover), room headers only have a
    single possible action - triggering the popover. It isn't really useful to
    restrict that to left clicks, so simply treat secondary button events as
    primary ones.
