            Bug ID: 169974
           Summary: The sizing of images in flex should take the dimension
                    change caused by definite cross-size and aspect-ratio
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

Steps to reproduce:

1. Define a width/height on a flex
2. Insert an image in it
3. Observe how its aspect-ratio affects its final size

Did this work before? N/A 
Does this work in other browsers? Yes


Actual results:

Images do not flex as they do in Edge, which has been deemed per-spec in this case (see below). 


Expected results:

Aspect-ratio should be preserved, except if the image is to be sized bigger than its normal size ("grow" test case). If it is, the flexing that takes place as a second step will shrink the image to fit the container. 

The reason flexing is different is that flex-shrink is 1 by default and flex-grow is 0 by default. Flexing doesn't have to take the image aspect-ratio into consideration, but should also refuse to shrink further than the image intrinsic size.

Please discuss this issue at https://github.com/w3c/csswg-drafts/issues/1112 if you disagree with the test results
