Adding a custom renderer changes the tap behavior

[andyszy]

When I don't have a custom renderer, clicking on the right half of the component advances to the next story, as it should be.

As soon as I specify a custom renderer (even if it's just an empty component), clicking on the right half of the component pauses the story. If I click a second time, it advances to the next story. I can't figure out any way to get back to the correct behavior.
