Issues with width parameter on AMP images and iFrames

[gbaumbach]

I've got an image on this page with this code rendering oddly in AMP:
<img alt="Up to twelve months, four phases, one client. You." data-image="4859" src="/upload/Graphics/12months-4phases-1client.jpg">

The rendered output after I use Amplify is:
<amp-img alt="Up to twelve months, four phases, one client. You." data-image="4859" src="/upload/Graphics/12months-4phases-1client.jpg" width="f" height="a" layout="fixed" class="i-amphtml-element i-amphtml-error"></amp-img>

Also, for an iFrame that has a width set to 90%, AMPLIFY keeps the width="90%" parameter which fails AMP inspection. If these could possibly be fixed, that would be most excellent!
