Steps to reproduce the problem:
1. Enable the experimental-web-platform-features flag
2. Create a div element with the styles width: auto; height: 100%;
3. Call getComputedStyleMap for that element
4. Look at the width and height properties of the map

What is the expected behavior?
The computed values `auto` and `100%` should be shown in the console

What went wrong?
The resolved values `1920px` and `0px` are shown instead

Did this work before? N/A 

Does this work in other browsers? N/A

The spec <https://www.w3.org/TR/2016/WD-css-typed-om-1-20160607/#dom-window-getcomputedstylemap> states:

> The StylePropertyMap returned by getComputedStyleMap represents computed style,
> not resolved style. In this regard it provides different values than those in objects
> returned by getComputedStyle.
