Hi,
This issue only happens in IE11. Do not happen in firefox, in chrome, in IE9 and IE 10.

When creating a user, when i leave the username field, the field is erased and the cursor goes to First name.
Inthe IE11 console, i have the error:

DOM7011: The code on this page disabled back and forward caching. For more information, see: http://go.microsoft.com/fwlink/?LinkID=291337

Steps to reproduce:

• Access the option to create a user
• Fill in "Username" and exit the field.

In last step, the cursor goes to "First name" and the username field is wiped.
