button element: background-color:transparent is ignored

[andreacremaschi]

Hi, let's say there is a UIButton created in the IB with white background. This is being styled in SCSS with the following code:

button.push:normal {
    color: $white;
    background-color: transparent;
    background-image: url(menu_button_green.png);
}

What happens is that the UIButton is styled with the correct image but the background image is still solid white. If I change the code above with this:

button.push:normal {
    color: $white;
    background-color: $red;
    background-image: url(menu_button_green.png);
}

The background color is correctly changed to red. Freestyle seems to ignore the "background-color:transparent" attribute for buttons but not the "background-color:$red"
