Icons in header menu offset after update

The last update broke the icon layout in the header menu.

Problem is because of newly introduced CSS:

.navbar .navbar-nav>li a i {
    min-width: 30px;
    text-align: center;
    position: relative;
    top: 2px;
    margin-top: -4px;
    margin-right: 4px;
}

The top and min-width are breaking the layout.
