Current behavior When showing a form in IE 11 with an input field, the initial state of the field is not pristine, leading to error messages being shown to the user before he touched the field.

Expected behavior The field state should be pristine until the user first entered and removed some text. This works fine in e.g. Google Chrome

Minimal reproduction of the problem with instructions http://embed.plnkr.co/fm7lH2/ The red error message should only be display when the user entered and removed some text.

What is the motivation / use case for changing the behavior? Form validation errors should only be displayed when a user touched the form.
