IE: $('<form>') don't works properly

IE: $('<form>') don't works properly

Hi again!
I have a new bug for jQuery :p ok, not is good :/

Well, is simple: if you make a <form> in IE, and don't close /> or </form>, this don't will be recognized :S Really, strange. In Chrome, Opera and Firefox works fine.

Test:
- Work in all:  http://jsbin.com/akuye3/8
- Don't work in IE: http://jsbin.com/akuye3/9

What occur:
- When you open the test page, will show an alert;
- When you click in "CLICK HERE", will post page and show an alert again;

In IE, the second case don't occur.
See the source code for more details.

Bye.
