Week Number can be hidden, but can't be revealed

I right-clicked on the week numbers on the left side of the calendar grid. There is a menu option to "Hide Week Numbers". After clicking this menu option, the week numbers slide out of view. Now I can't get them back.

This looks to be an older feature that had the show/hide option removed at one point, but the functionality is still there. The only way I can find to bring the week numbers back is to open up dconf editor and change the appropriate setting.
