| Verify that an image valued shape-outside layout is updated after the image has |
| been loaded. This test checks that the left edge of the "Hello World" text span |
| is defined by the 200px wide float before shape-outside image has been loaded and |
| by the 100px wide image segment after it has been loaded. |

| var s = document.getElementById("container").getBoundingClientRect(); |
| var r = document.getElementById(elementId).getBoundingClientRect(); |
| return {left: r.left - s.left, top: r.top - s.top, |
| width: r.width, height: r.height}; |
| } |

| assert_equals(elementRect("text").left, 200, 'image not loaded'); |
| |
| window.onload = t.step_func_done(() => { |
