Hidden facet value bug

[zepheiryan]

Sometimes facet updates end up invisible to the end user. The apparent invisibility seems to come from no dimensionality in the facet values (specifically the values, the container retains its size) - no height, no width, so seemingly no display. It's only when a dimension is requested, like $(element).height(), that they regain the correct dimensions and show up. This seems to point to a jQuery library bug, but it's not clear if that's correct.

Ugly work around in 98aa888 which should eventually be replaced by a true fix.
