这个BUG会影响到avalon的UI组件，触发widgetVM的$remove方法……

  if (supportMutationEvents) {
                        elem.addEventListener("DOMNodeRemoved", function(e) {
                            if (e.target === this && !this.msRetain ){
                                offTree()
                            }
                        })
                    } else {
                        elem.offTree = offTree
                        launchImpl(elem)
                    }

现在修正如下

  if (supportMutationEvents) {
                        elem.addEventListener("DOMNodeRemoved", function(e) {
                            if (e.target === this && !this.msRetain &&
                                    (window.chrome ? this.tagName === "INPUT" && this.relatedNode.nodeType === 1 : 1)) {
                                offTree()
                            }
                        })
                    } else {
                        elem.offTree = offTree
                        launchImpl(elem)
                    }
