mx:Legend fontSize not working - apache-flex

Question

I have a PieChart... now that I'm moving to support tablets as well, I need to make the fontSize of the legend larger. However, the following has no effect:
<mx:Legend dataProvider="{industryChart}"
height="110" bottom="40"
height.groupTablets="220" bottom.groupTablets="80"
fontSize="8" fontSize.groupTablets="16"
markerHeight="10" markerHeight.groupTablets="20"
verticalGap="3"
/>
I know that the state is correct because the other attributes change.
I've also tried adding a style section:
<fx:Style>
.legend {
fontSize:24;
}
</fx:Style>
<mx:Legend dataProvider="{industryChart}"
height="110" bottom="40"
height.groupTablets="220" bottom.groupTablets="80"
markerHeight="10" markerHeight.groupTablets="20"
verticalGap="3"
styleName="legend"
/>
No change. Nor does it work if I move the style to Main.css.
Using this gives a warning: CSS type selectors are not supported in components: 'mx.charts.LegendItem':
<fx:Style>
#namespace mx "library://ns.adobe.com/flex/mx";
mx|LegendItem {
fontSize:24;
}
</fx:Style>
But if I put the same in Main.css, it does work:
#namespace mx "library://ns.adobe.com/flex/mx";
mx|LegendItem {
fontSize:24;
}
The problem I have with that is that I have to be able to make the font larger when in the tablet state, and not just for all states, or the font will be too large on a phone.
Pseudo-selectors don't appear to work:
mx|LegendItem:groupTablets {
fontSize:24;
}
IDs do not work, in either Main.cc or fx:Style:
#pieLegend {
fontSize:24;
}
<mx:Legend id="pieLegend"
dataProvider="{industryChart}"
height="110" bottom="40"
height.groupTablets="220" bottom.groupTablets="80"
markerHeight="10" markerHeight.groupTablets="20"
verticalGap="3"
/>
However, even if that approach worked it would have difficulties when the code behind the mxml needs to reference a particular component by id.
I even got frustrated and tried this in the code:
pieLegend.setStyle("fontSize", 24);
Nope. Grrrr.
Any ideas?

Caught the same issue. Here's from the adobe forum, might have to wait for apache flex for a real fix:
The problem is based on a bug that was deferred ( http://bugs.adobe.com/jira/browse/FLEXDMV-1656). There are several workarounds, but the simplest is to set the fontSize on the LegendItem type selector, like this:
<mx:Style>
LegendItem {
fontSize:24;
}
</mx:Style>
