Family sort order sorts on birth year, not on birth date


When I click on the "Birth" column header in the Family list on the right side of Family.Show, the sort order changes to that column, but as you can see on the attached image, it's not sorted on the full birth date, which gives strange results in the Age column (as you can see on the image). Could the sorting mechanism use the full birth date? Probably Death date has the exact same issue.
