Bug 1374540 part 1: Add reftests to verify that used 'flex-basis:content' resolves to the max-content size on flex items in row-oriented flex container. r=mats
Note: These tests fail in current mozilla-central (and hence are marked as failing), but they start passing as of a patch later on in this series. MozReview-Commit-ID: ElWJCl1ki0H --HG-- extra : rebase_source : a5bdb9afae0a3bb902834d07c4c22783c8904104
