Actually navbar background color is transparent for hover state.
.navbar .nav > li > a:hover {
background-color: transparent;
color: @navbarLinkColorHover;
text-decoration: none;
}
For a better control/customization please add a @navbarBackgroundHover color definition...
However i'm not sure if it's more consistent to have a @navbarBackgroundHover (same pattern as @navbarBackgroundHighlight), or a @navbarLinkBackgroundColorHover as it's more close to what it is really...
