AMP-Carousel with varying image dimensions

Question

I'm struggling to create an AMP-Carousel with images which have varying dimensions. I want to scale the images in the carousel to a fixed height & an automatic width.

The examples provided in the docs all have the same width/height.

I've tried leaving out the width for the amp-img elements & using layout="fixed-height" but that didn't work at all. The docs are very confusing.

<amp-carousel width=500 height=300>
    <amp-img src="http://placehold.it/200x600" width=200 height=600></amp-img>
    <amp-img src="http://placehold.it/700x550" width=700 height=550></amp-img>
    <amp-img src="http://placehold.it/340x410" width=340 height=410></amp-img>
</amp-carousel>

I've created a js-fiddle to show you what I've got & what I want

Edit:

The styles are not consistent with the docs or I don't get them?
On the amp-carousel page it says: Layout not supported for: responsive but on the demo page the amp-img elements have layout="responsive"

You have to use the fixed-height layout and give carousel and all images the same height. The width needs to be updated accordingly to keep the aspect ratio. Example:

<amp-carousel height=300 layout="fixed-height">
    <amp-img src="http://placehold.it/200x600" width=100 height=300></amp-img>
    <amp-img src="http://placehold.it/700x550" width=381 height=300></amp-img>
    <amp-img src="http://placehold.it/340x410" width=248 height=300></amp-img>
</amp-carousel>

Automatically adjusting the width is currently not supported.
