IE11 window name is reset to the original after every load

IE iframe window name is reset back to the original after every load.

Steps to reproduce:

1. Create a form with a target set to iframe named NAME-A.

2. Submit a form method=A

3.  on load A sets window name to NAME-B

4. IE returns iframe.contentWindow.name = NAME-B (correct)

5. change iframe src to B

6 B is not making changes to window.name.

7. on load iframe.contentWindow.name is set back to NAME-A (incorrect, since it wasn't changed and should still be NAME-B).

Thanks.
