How can I react meaningfully to a changeAttributes: delegation pass-through from WebView?

Question

Have you looked at the source code?

WebHTMLView.mm

I don't see how -changeAttributes: is calling -webView:doCommandBySelector:, as within this class it's only called inside its own -doCommandBySelector: method.

- (void)changeAttributes:(id)sender
{
    [self _applyStyleToSelection:[self _styleForAttributeChange:sender] withUndoAction:EditActionChangeAttributes];
}


- (void)doCommandBySelector:(SEL)aSelector
{
…
    if (![[webView _editingDelegateForwarder] webView:webView doCommandBySelector:aSelector] && coreFrame) {
…
}

Also, why can't you subclass WebHTMLView? Is it because of the Mac App Store restrictions on API? Does WebKit count as private? I thought it was Open Source.
