Fix dashboard totals in older IE versions
Fix dashboard totals in older IE versions

The layout of the totals on the dashboard was getting horizontally
squashed on older versions of IE.

This was something to do with the `grid-row` CSS class no longer being
applied when AJAX updated the page. Grid columns don’t work properly
unless they’re contained in a grid row.

This commit wraps the `div` with `grid-row` in another `div`. Not
totally sure why this works, but it’s something to do with how the
DiffDOM algorithm is working. Seems like the simpler the diff it has to
compute, the better chance it has of not messing things up.
