Description
What if we want to control the layout this way:
- The height is determined by the content
- The max-height is determined by a specified aspect ratio
Example:

The aspect-ratio allows determining the preferred aspect ratio, but sometimes it's not a fixed aspect-ratio, but a range. In the example I don't want the container to be taller than 1:1.

Research direction
Start by reading the CSS Sizing Level 4 issue and its discussion of aspect-ratio limits for image containers. Compare the requested content-determined height and ratio-based max-height behavior with the existing specification context. Done means the working group has a clear resolution for whether and how this range-based behavior should be specified.
