You threw me for a moment there. The menu item is enabled (ie, not grayed), it just doesn't do anything when clicked. Similarly with header, base precinct, report precinct, district, and vcenter.
Not sure what we really want to do here, especially for the 1.11 series. Sure, adding a race to the list view when the race root tree item is selected makes sense. But what if they were instead looking at the race tab of some selected report precinct in the tree view? You can't add a race dirctly to a report precinct, you need a district.
Tab, you wanna look at this?
