CSS Color of limits from UI-Gauge not working

### Current Behavior

When I configure te colors of the UI-Gauge the color is not respected and is dimmed. It also flickers on Fully Kiosk Browser when using Hardware Acceleration. I think the color is adjusted in javascript somewhere.

.nrdb-ui-gauge #limits text {
color: #FFF !important;
fill: #FFF !important;
}

### Expected Behavior

When I configure the color of ui gauge limits the CSS should be respected and not dimmed and shouldn't flicker in Fully Kiosk Browser.

### Steps To Reproduce

Open a UI-Gauge in a browser with the css and see the colors are not respected.
