NSTextView, undo does not reset typingAttributes

Subject: NSTextView, undo does not reset typingAttributes

I just noticed this behavior, which has been around at least since Tiger. Select some text in a NSTextView and then change a text attribute, such as font or foreground color. Then undo the change. Without clearing the selection, start typing. The new characters appear with the attribute that you have just undone. It looks like Undo is undoing changes to the model, but not undoing changes to the text view's typing attributes.

It's a simple thing to work around, but I wonder if that behavior exists for a reason. Does anyone see a problem with setting the typing attributes to the NSTextStorage's attributes after every undo/redo?
