F2F Notes: Gottfried mention replacement for active value:
@media screen and (high-contrast) /* any high-contrast value */

Instead of:
high-contrast-adjust: auto | none;

Consider:
high-contrast-noadjust: auto | all | property list;

example: okay to override :focus pseudo-class 'outline' property on this element, but not okay to override 'background-image' property:

.replaced {
outline: solid 1px red;
background-image: url(foo.png);
high-contrast-noadjust: background-image;
}
