An image with height:100% and width:auto is not updated properly on relayout. When the height of the parent is changed, the height of the image is adjusted, but the width does not change. See: http://jsbin.com/wevitageka/1/edit?html,output

We don't have broken behavior screenshot but based on JSBin, I am getting same behavior across all browsers (Safari Technology Preview 189, Firefox Nightly 124 and Chrome Canary 125) in rendering. So I think we can close this.
