Hello, On a flex-direction: column container and a flex:1 children, min-height which should be "auto" is computed to "0" and content can be hidden. See : http://codepen.io/raphaelgoetter/full/dpqjZO/ This bug is not listed on https://github.com/philipwalton/flexbugs

All browsers behave the same here, so seems fixed (already worked fine).
