I'm working on a very important project in which the customer is asking for epub3 popup footnote functionality to be on the "cutting edge" (cringe) when compared to competitors' books. I've got everything setup for the popups, but I've run into an issue with very long footnotes.

In iBooks, when I tap on one of the very long footnotes, the popup window spans the height of the iBooks window. However, the popup window, even when the Books app window is maximized, isn't big enough to contain all of the footnote text. And there's no scroll bar to view the entire footnote in the popup window. I'm seeing this behavior on the Books app on a Macbook Pro.

Does anyone know if there's any trick to enabling a scroll option or changing the size of the popup window? I'm assuming not, because I don't see any documentation on it at all. But I wanted to check here before breaking the news to my client.
