jQuery 1 throws an error on window ready when there is an element in the DOM with the id 'nodeName'

[me@…]

When triggering the window ready event jQuery 1, since version 1.8.0, throws the error:

  Uncaught TypeError: Object #<HTMLSpanElement> has no method 'toLowerCase'

on the line:

    var noData = elem.nodeName && jQuery.noData[ elem.nodeName.toLowerCase() ];

The error is thrown when an element exists in the DOM with the id: "nodeName" or window.nodeName is defined as something

This is caused by passing the window object into acceptData, which is meant for DOM Elements. When the nodeName property is defined on the window object to be anything which doesn't have a toLowerCase function, the error is thrown.

Well, that's strange. This is certainly not high priority, but acceptData could probably check nodeType === 1 instead.
