I just had a look – this behavior seems to occur due to the “pull-to-refresh” feature of the ListPage.
This feature is active in the main page of the twitter demo. and the current implementation prevents clicks to get through to the list-items.
We will fix this bug for the next update – if you don’t need “pull-to-refresh” you can safely use the ListPage without experiencing this issue.
Thanks a lot for reporting this bug!
