In the Felgo/Examples/Twitter example on both iOS and android, if you tap the Nth item on the list, then the detail page is not shown. However if you scroll down slightly (1cm) — so the top item is slightly hidden — then you can tap the Nth item on the list to see the detail page. Play around, and you’ll see that if the 1st item is completely visible, then you can’t select items to see details.
Inspecting MainPage.qml makes it appear like a bug in the ListPage component.
