Christian Biesinger 051ed9a783 Bug 1499529 [wpt PR 13550] - [css-flexbox] Apply min-height: auto to nested flexboxes again, a=testonly
Automatic update from web-platform-tests[css-flexbox] Apply min-height: auto to nested flexboxes again

This was made possible by crrev.com/c/1283482, which avoids the
performance and correctness issues this previously caused.

This relands crrev.com/c/1246730 / crrev.com/c/1252682. The ChromeOS UI
breakage was fixed by crrev.com/c/1281726 and crrev.com/c/1282462

IF THIS BREAKS ANY FURTHER CHROME UI:
Please don't revert this patch; instead, add min-height: 0 to any
inner nested flexboxes that may be affected by this patch. This is
an important change for web interop with the other browsers.
