Tooltip help text too big on mobile

[aussig]

The new tooltip help text is a bit big on mobile.

e.g.: http://www.opensceneryx.com/objects/ground_features/snow_piles/3/

Available since and Dimensions are fine, while Seasonal variants has a huge tooltip.

Not clear what's causing this. The markup is identical and it performs correctly on a narrow desktop browser window. The only apparent difference is the amount of content in the tooltip, where more content could be making it larger - perhaps this has a bearing?
