Web Inspector: Classname stuff in WebInspector.displayNameForNode should join DOMTokenList classList instead of using string parsing and concatenation. Unless I'm missing something, I expect this was just written before DOMTokenList classList was available.

    var classAttribute = node.getAttribute("class");
    if (classAttribute) {
        var classes = classAttribute.trim().split(/\s+/);
        var foundClasses = {};

        for (var i = 0; i < classes.length; ++i) {
            var className = classes[i];
            if (className && !(className in foundClasses)) {
                title += "." + className;
                foundClasses[className] = true;
            }
        }
    }

node is not a real DOMNode, it is our DOMNode proxy. So we don't have access to classList unless we go to the injected script for it. That is why we do what we do here.

Gotcha. Makes sense.
