Chrome and firefox show "auto" as a single value, w3c too

That's technically correct, but the spec also says:

The first value gives the width of the corresponding image, the second value its height. If only one value is given the second is assumed to be auto.

So auto is a kind of shorthand for auto auto.

I think it may be clearer to list both values. (Feel free to reopen if you have more arguments).
