Animated GIF--Loop Just Once?

I created an animated GIF in Adobe Fireworks. It's a gauge with a needle that moves from the 6 o'clock position to the 12 o'clock position, using 16 frames ('states' in Fireworks parlance). I set the animation to run just ONCE; the needle rotates from 6 o'clock and stops at 12 o'clock. I tested the animated GIF in my Web browser and it works as expected.

When I insert the animated GIF onto a Storyline slide, however, the animation loops forever. It loops in Preview mode and also when I publish to Web (HTML) output.

Does Storyline recognize and respect the 'looping' setting contained within an animated GIF file?
