-/**
- * Works around bugs in the handling of {@link ViewTreeObserver} by
- * {@link PopupWindow}.
- * <p>
- * <code>PopupWindow</code> registers an {@link OnScrollChangedListener} with
- * {@link ViewTreeObserver}, but does not keep a reference to the observer
- * instance that it has registers on. This is problematic when the anchor view
- * used by <code>PopupWindow</code> to access the observer is detached from the
- * window, as it will revert from the shared <code>ViewTreeObserver</code> owned
- * by the <code>ViewRoot</code> to a floating one, meaning
- * <code>PopupWindow</code> cannot unregister it's listener anymore and has
- * leaked it into the global observer.
- * <p>
- * This class works around this issue by
- * <ul>
- * <li>replacing <code>PopupWindow.mOnScrollChangedListener</code> with a no-op
- * listener so that any registration or unregistration performed by
- * <code>PopupWindow</code> itself has no effect and causes no leaks.
- * <li>registering the real listener only with the shared
- * <code>ViewTreeObserver</code> and keeping a reference to it to facilitate
- * correct unregistration. The reason for not registering on a floating observer
- * (before a view is attached) is that there is no safe way to get a reference
- * to the shared observer that the floating one will be merged into. This would
- * again cause the listener to leak.
- * </ul>
