Image size / not keeping aspect ratio

**Describe the bug**
When i add styles to the I can set up a height but width auto don't work in combination.

```

```

**Expected behavior**
height: 80px
width: auto - so image should be not deformed

So if image is 400x120px (width x height)
Image should have when i set height 267x80px(width x height)

But only height is now 80px and width stay on 400px.

The problem is that is dynamic content so each image could be different.
