Clicking on panel clock applet should bring up current day

Version: ii unity 0.2.46-0ubuntu5 Unity Interface for Ubuntu Netbook Edition

In Gnome, if I click the date/clock applet in the upper panel, it opens a monthly calendar that highlights the current date. With the Netbook edition, if I do the same, the current date is only displayed the first time I open it. If I scroll the calendar or click on a different day, that day will forever be highlighted each time I click on the clock applet until I change it again. Unity should behave like Gnome.
