[css-sizing-3] max-content contribution of replaced only-aspect-ratio elements might be improvable · Issue #4218 · w3c/csswg-drafts (original) (raw)

Chrome gives it 0x0, Firefox gives it ICB width and then ratio height. The spec says 300px width and ratio height.

We suggest to go with FF's behavior, as this seems more useful than 0, and less arbitrary than 300px.
