When the CSS processor "supports" a value BUT the OS prevents the 
support from actually occurring what would be the result?
For example. Would
@supports (background-color: #CCC) return true or false when running in 
Windows High Contrast mode where background colours are not applied.

It would be very useful if this would return false - so this situation 
could be detected in CSS and appropriate styles applied.
