-  // Bookmark bar folder controller chains are torn down in two ways:
-  // 1. Clicking "outside" the folder (see use of
-  // CrApplicationEventHookProtocol in the bookmark bar controller).
-  // 2. Engaging a different folder (via hover over or explicit click).
-  //
-  // In either case, the BookmarkButtonControllerProtocol method
-  // closeAllBookmarkFolders gets called.  For bookmark bar folder
-  // controllers, this is passed up the chain so we begin with a top
-  // level "close".
-  // When any bookmark folder window closes, it necessarily tells
-  // subcontroller windows to close (down the chain), and autoreleases
-  // the controller.  (Must autorelease since the controller can still
-  // get delegate events such as windowDidClose).
-  //
-  // Bookmark bar folder controllers own their buttons.  When doing
-  // drag and drop of a button from one sub-sub-folder to a different
-  // sub-sub-folder, we need to make sure the button's pointers stay
-  // valid until we've dropped (or cancelled).  Note that such a drag
-  // causes the source sub-sub-folder (previous parent window) to go
-  // away (windows close, controllers autoreleased) since you're
-  // hovering over a different folder chain for dropping.  To keep
-  // things valid (like the button's target, its delegate, the parent
-  // cotroller that we have a pointer to below [below], etc), we heep
