For a web designer, it would be useful to be able to tell UI Options to not remove the background images from a container.

For example, Google Maps uses background images to display its map information - turning on a contrast theme will make it disappear. In this case, the web designer will need to create a specific rule (with !important) to override UIO. It would be better if there was a class we can apply to such containers instead of resorting to an !important arms race.

i.e.
<div id="map" class="uioc-keep-background">...</div>
