Automatic update from web-platform-tests [css-layout] Don't let contain-intrinsic-size establish an aspect ratio contain:size on a replaced element kills its natural aspect ratio. Blink had been treating contain-intrinsic-size values as establishing a new aspect ratio, but this was not supposed to happen. E.g. the following should have no aspect ratio: <img src="100x100.png" style="contain: size; contain-intrinsic-size: 40px 20px"> This change has the side effect of making HasAspectRatio() logically imply !GetAspectRatio.IsEmpty(). Flex has a DCHECK enforcing that logical relationship, which was triggered in the canvas test case in this patch.
