i've a TabBar that after the last Chrome upgrade (32.0.1700.76 m) is displayed with an outline on focused tabs:

In past version there wasn't. To restore old view i tried to set some outline in CSS, like this:
.gwt-TabBar .gwt-TabBarItem:focus {
outline: lime auto 5px !important;
}
(lime is just for see if it works).
Even this edit, the computed style still remains the default (-webkit-focus-ring-color auto 5px;
):

What should i do to override this user agent style?
EDIT
I think the blue outline is not of the HTML (div):




The one i want to put away is on the TabBar Item object:




I honestly don't know why the Churro solution worked before :(
