We changed our rendering to match the flexbox specification and other browsers. In previous versions, Chrome did not implement the automatic minimum size for the specific case of a column flexbox containing a flex item that is itself a flexbox. We have now changed this so that such flex items do get the right minimum size. This can cause flex items to not shrink anymore when they used to; to avoid that, set min-height: auto on the flex item.
