Several previews on that site seem to show a sans font, with saner line-height. My guess, the preview trashed your font-family and possibly font-size, but not your line-height; and your chosen line-height is too tight for their fallbacks for the former two. I’d start by unsetting any line-height on p. It’s not that useful to set that anyway, as it’s a common user control.

Edit: just noticed hitch basically already said this above. One of these days I may learn to read.

Distributors don’t alert you to aesthetic issues unless customers complain, because these things are heavily automated so they don’t usually know about them otherwise. Also, previews like this are not really representative of the delivered product, necessarily. Obviously still troublesome in situations like this.
