Re: [csswg-drafts] [css-sizing-4] How to interpolate contain-intrinsic-size: auto 10px to 20px (#6566)

My understanding is that given `auto <length>` is a separate kind of value type, it should not be interpolable if the auto value does not match on both sides. I.e. the entire thing (both auto and length) should flip at 50%.

In general, we don't interpolate from auto values to non-auto values, see [width example](https://jsbin.com/pecemiq/edit?html,css,js,output), so if we did interpolate the length and flip the auto you would end up animating from a value that the user never saw if it was using the auto value.
