https://github.com/WebKit/webkit/blob/2f5ab3dcd0f5d3b6bc36bf46582cee8f76226db4/Source/WebInspectorUI/UserInterface/Views/LogContentView.js#L976 messageView.element doesn't exist when the console hasn't been shown yet. Now that I moved _filterMessageElements to didAppendConsoleMessageView, we should be able to just remove it here.
