Programatically change DOM styles via the Objective-C interface doesn't
automatically update the display in the WebView.

Consider the attached example.

Build and run.
Click the Change DOM button.

The changes are not immediately visible. Mousing over the web view makes the
change visible.

Sending the webview a -setNeedsDisplay:YES or sending
-setNeedsToApplyStyles:YES to the document view doesn't work around the problem
either.

The code which manipulates the DOM looks like this:

        DOMDocument *document = [[webView mainFrame] DOMDocument];
    DOMElement *element = [document getElementById: @"foo"];
    DOMCSSStyleDeclaration *style = [element style];
    [style setBackground :@"red"];
