Error reading 'href' attribute in IE when userData Behavior is applied

userData Behavior <> is a local storage implementation in IE.

jQuery calls getAttribute("href", 2) in IE to read the 'href' attribute of an element.

Apparently if userData Behavior is applied to an element and getAttribute() is later called on the same element with more than one argument the result is an error.

Steps to reproduce in IE7:

var a = $('<a href="#foo"/>');
a.attr('href');  // Error: Wrong number of arguments or invalid property assignment

As far as I can tell this affects IE6 and IE7. I encountered this error when using jQuery in combination with persist.js.

Looking further into this I see that elements with userData enabled have an expires attribute with an - often empty - string value. Elements that do not have userData enabled generally do not have an expires attribute. So that attribute could be used in a check in Expr.attrHandle.href(). Though I don't know of any way to get an unmodified href value from an attribute after it has userData enabled.

So what happens to the href value? It becomes impossible to get the non-normalized value?

That's because the href attribute is removed when you use the behavior.
