Automatic update from web-platform-tests [css-flex] Obey stretch size in replaced items' content size suggestion Content size suggestion is just min-content size. The min-content size of a replaced element is supposed to account for preferred size in the opposite axis. We were not doing that for content size suggestion when the opposize axis preferred size came from a flexbox's fixed cross size. In the example below, Blink now gives the image content size suggestion 100px because 100 = 300*150/50. Before this patch Blink gave it a content size suggestion equal to its natural width 300px. <div style="display: flex; height: 50px;"> <img src="support/300x150-green.png"> </div> Firefox matches Blink's behavior before this patch. We may have compat issues. See https://github.com/w3c/csswg-drafts/issues/6693 for discussion of this new behavior.

content size suggestion is 100px because the image has a stretched height of 50px. So min-content size of the image is 300x150/50 = 100.
|
|
specified size suggestion is 150px
|
|
transferred size suggestion is 100px
|
|
|
|
transferred size suggestion is ignored because there is a specified size.
|
|
|
|
So here the content-based minimum size is min(100px, 150px) = 100px
