Popup window font size in full screen mode

[Guntis]

When I open any commentary in the full screen mode and click-and-hold any Bible link, popup window opens and shows me that text. However, for the full screen mode it would be nice if that text would be 2-3 steps larger. Can you make a different font size for the full screen mode? Perhaps the same size as the main commentary text in the full screen mode, or a notch smaller.
