Firefox doesn't implement the svg.getIntersectionList function, which means marking in Word Cloud completely fails (leaving boxes on the screen instead).
Thanks to Fran Spielgel for reporting this via the Spotfire community.
I'll either need to ditch marking from the Word Cloud on Firefox, or make a lot more effort to resolve the fact that browsers don't do intersections of SVG elements very well (Chrome does it, but it's bounding box based rather than real intersection, meaning that sometimes weird effects occur and things mark that weren't selected).
