Firefox does not print drawn shape "extent"

[JoanSteinbacher]

My app provides users the ability to draw various shapes on a map.  Oddly, when printing the map (using ESRI's print service), the "Extent" shape is not displayed in the printed map.  All other shapes are displayed on the printed map as expected.  This only occurs in Firefox (I've tried versions 17.0.1 and 19.0).  Can anyone explain this behavior or provide a fix?  Below is the pertinent html and javascript code.

The app itself is here: http://gis.tpcmaps.org/apps/production/pima

Thanks,
Joan
