For flexbox items the default value was changed from min-content to 0 in https://bugs.webkit.org/show_bug.cgi?id=111790 and later reported as a regression https://bugs.webkit.org/show_bug.cgi?id=114566. Since then the spec has changed and now it's clearly specified both the default value for those properties and also how to compute the minimum size for flex/grid items.

The fix involves merging the following Blink change logs: * for flexbox - https://crrev.com/193665 - https://crrev.com/194062 - https://crrev.com/195930 * for grid - https://crrev.com/194408 - https://crrev.com/194863 * for both https://crrev.com/194887 That's why I'm converting this into a meta-bug to land flex and grid changes independently 1125585 2 svillar 2015-09-14 05:54:56 -0700 Closing as all dependent bugs were fixed.
