I was able to reproduce. Improving the error message, I see two issues:

NavigationSidebarPanel.js:234:26: CONSOLE ERROR Error: TreeElement.representedObject is missing a saveIdentityToCookie implementation. TreeElement.constructor:  class ApplicationCacheManifestTreeElement extends WebInspector.StorageTreeElement

ContentView.js:149:132" CONSOLE ERROR Error: Can't make a ContentView for an unknown representedObject of type: ApplicationCacheManifest
