| <!-- This testcase checks flex items are painted atomically. In particular, |
| if one item has content that overflows into the region of another item, |
| then one item is painted "behind" the other; there shouldn't normally |
| any interleaving of backgrounds and content between the two items. |
| |
| This testcase also tests some special cases that will change the paint |
| ordering - specifically, the properties "position", "z-index", and |
| "order" on flex items. |
