The selection details "windows" contain frequently updated text and can be moved around in the scene. We don't want their contents to be batched with the rest of the scene as there may be many events in the timeline and rebuilding the batch they are in is expensive. The clip property has the side effect of preventing nodes within the clipped area from getting batched with nodes outside it. Thus, by setting the clip property on the details we reduce the number of batch rebuilds for the actual timeline. Having a transparent rectangle in there doesn't help the renderer, either, so we replace it with a plain item.
