6 <!-- This testcase checks that flex items are painted as pseudo-stacking
7 contexts, instead of full stacking contexts. In other words, content
8 inside of one flex item should be able to iterleave between pieces of
9 content in another flex item, if we set appropriately interleaving
10 "z-index" values. -->
