Summary: Uncaught Exception: null is not an object (evaluating 'this.listItemElement.classList') Steps to Reproduce: 1. Inspect Element on an element deep in Shadow DOM => exception, element not selected in DOM Tree Notes: - The updateTitle is happening onexpand before the element is attached. The <li> is not created until attached. - This alludes to some performance opportunities. Do we need to update title on expand if not yet attached? ------- Uncaught Exceptions: - null is not an object (evaluating 'this.listItemElement.classList') (at DOMTreeElement.js:1257:45) _nodeTitleInfo @ DOMTreeElement.js:1257:45 updateTitle @ DOMTreeElement.js:1133:55 onexpand @ DOMTreeElement.js:506:25 expand @ TreeElement.js:391:26 reveal @ TreeElement.js:437:39 revealAndSelect @ TreeElement.js:515:20 _revealAndSelectNode @ DOMTreeOutline.js:291:36 selectDOMNode @ DOMTreeOutline.js:132:34 selectAndRevealDOMNode @ DOMTreeContentView.js:141:43 showRepresentedObject @ ElementsTabContentView.js:82:50 showRepresentedObject @ Main.js:1120:41 showMainFrameDOMTree @ Main.js:1128:31 _domNodeWasInspected @ Main.js:1784:30 dispatch @ Object.js:170:30 dispatchEventToListeners @ Object.js:177:17 inspectElement @ DOMTreeManager.js:313:38 nodeAvailable @ DOMTreeManager.js:331:32 nodeAvailable @ [native code] ? @ DOMTreeManager.js:108:21 _dispatchResponseToCallback @ InspectorBackend.js:311:27 _dispatchResponse @ InspectorBackend.js:281:45 dispatch @ InspectorBackend.js:157:35 dispatchNextQueuedMessageFromBackend @ MessageDispatcher.js:42:34
