$('form').prop("tagName") won't return correct tag name

[wenxuan.mo@…]

For an HTMLFormElement, prop("tagName") won't return "form" if it has a child whose name property is "tagName", it returns this child node (object HTMLInputElement) instead.

Same thing happens with plain DOM though.

yeah, thanks for sharing the domlint. I agree that technically this is not a bug with jQuery, but it would be much better if jQuery can fix this up so that I can use jQuery selector and prop() function to avoid conflicts using plain DOM.

It would be great if we could fix everything, but unfortunately we can't.
