Breaks jQuery data()

When "show internal jQuery data" is checked, returning of data() in jQuery breaks (on whole site)

jQuery("body").data("foo", 1);

jQuery("body").data("foo");
     returns undefined

It seems that .data("key", value) adds a data property inside the data property of an element.

Without ShowInternalData enabled, I can't see events or data properties on elements. When it's on the above happens.

Any ideas?

Not sure its related, but I get a similar problem. With "show internal jQuery data" checked, the following fails (alert displays undefined):

$(function () { 
   $('body').data('hello', 'world'); 
   setTimeout(function () { 
      alert($('body').data('hello')); 
    }, 0); 
});
