Depends on relative humidity ...
Even if the ambient air is extremely dry, the low temperature of the ice cream bar means that the micro-climate (at the immediate surface of the bar) will be at very high relative humidity. You won't see much moisture loss until the bar is melted and its temperature somewhere close to ambient.
