Do the libraries supplied by Google for supporting D-pad navigation within HTML5 handle long lists?

Looking for examples, I came across a page at Khan Academy that uses the jquery flavor of the libraries:

http://www.khanacademy.org/gtv/

When viewing that page on Google TV, I see a problem navigating down the list with the D-pad down-arrow key. Navigation just stops at a certain cell (Algebra:Logarithms), refusing to go further down.

What could be the problem? The source code looks fine–there isn’t much besides the library code–as it creates well-formed DIV tags to make up the long list. I tried copying files locally and replacing the libraries with the most recently published copy (from 2/2011)–no change.

The bug is described on the Khan issues site, along with another, and as a bug for GTV now too.

    There is a bug with Template Javascript file due to a hardcoded parameter rowsPerPage in index.js file. Please see the following issue for more detail.

    http://code.google.com/p/googletv-issues/issues/detail?id=29

    Once you increase this number to something like 100, it can accommodate long list like what Khan app has i.e. 49 items.
