This patch renames DispatchChromeOnly flag to OnlyChromeDispatch. With this patch, if OnlyChromeDispatch flag is set, and the target is already a chrome node, the dispatch path will start from the target. Previously, even if the target is a chrome node, the dispatch path starts from the parent target of the owner window of the current node.
