Bug 198032 – Inherited width does not respect max-width and min-width algorithm

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Andrew H]

if an inner element is positioned relative, and has both min-width and max-width specified where min-width > max-width, an outer element with position absolute won't receive the proper width value.

min-width / max-width algorithm: 10.4 @ https://www.w3.org/TR/CSS2/visudet.html#min-max-widths

JSFiddle demonstrating this behavior: https://jsfiddle.net/booc0mtaco/Lr9bzh07/ (chrome and firefox appear to resolve the width as expected)

Expected: outer wrapper (blue) should be as wide as the inner element due to the width algorithm.

Actual result: the outer element appears to simply take the max-width value, while the sized element does the proper calculation.

Could you please review this change?
And I wonder the included wpt test case will be merged automatically
to the wpt github repository.

At the command prompt below,

Would you like to export the web-platform-tests changes to a WPT GitHub repository? [Y/n]: y

I coundn't proceed the process smoothly(failed with some error in fact),
so I wonder I don't have to care about that wpt export failure message.

I've read https://lists.webkit.org/pipermail/webkit-dev/2017-December/029837.html,
and succeeded to update wpt test case with PR form using it.
So current state of this patch is that if this patch get r+, the included wpt test can be merged too into wpt github repo.
