"And X more..." option on calendar doesn't function

What is the expected behavior when you have more than the allotted (default = 3) events on a given day? The calendar updates to show "And {x} more...", but clicking on this doesn't seem to do anything. I've done some CSS changes and also updated the widget to raise the default up from 3, but I'm curious what is SUPPOSED to happen. Here's what I see:

Is it expected that the other events appear when clicking the "And X more..." button? Is clicking on a calendar cell supposed to do anything?
