An LLFolderView is added as child to LLScrollableContainerView, but also adds the LLScrollableContainerView to it's mScrollContainer. As a result, when scrolling inside a LLFolderView the event is passed to the mScrollContainer, which then passes it first on to it's children (see the "Bad UI design" remark in the code), causing an infinite loop. This patch breaks that loop for those objects that have a mScrollContainer: LLFolderView and LLContainerView.
