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.

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