Patch by Joseph Pecoraro <pecoraro@apple.com> on 2016-09-18
Reviewed by Matt Baker.
* UserInterface/Views/DOMTreeElement.js:
(WebInspector.DOMTreeElement.prototype.onexpand):
If not attached yet, don't update title. We will update title
when attaching, so this avoids work and avoids doing that
work when the tree element is not fully setup.
(WebInspector.DOMTreeElement.prototype._startEditing):
(WebInspector.DOMTreeElement.prototype._nodeTitleInfo):
(WebInspector.DOMTreeElement.prototype._nodePseudoClassesDidChange):
Switch to the public name instead of the private name.</pre>
