| <p>Bug 109616 - ASSERT(!layoutObject()->needsLayout()) when calling Element::focus() with generated content</p> |
| |
| <!-- |
| This is testing a case where LayoutQuote (anonymous)::updateDepth would mark the LayoutQuote (anonymous) |
| and its ancestors as needing layout in the middle of a layout of its ancestor. |
| When its ancestor finishes the layout it will mark itself and the ancestors |
| farther up as no longer needing layout. The end result is some subtree |
| needing layout, but the LayoutView and possibly other ancestors of the subtree |
| not needing layout. |
| |
| ex. |
| |
| LayoutView <- !needsLayout |
| \ |
| LayoutBlockFlow (.focusable) <- needsLayout |
| \ |
| LayoutBlockFlow (generated content) <- needsLayout |
| \ |
| LayoutQuote (anonymous) <- needsLayout |
| --> |
| |
| <div class="positioned"></div> |
| <div class="focusable" tabindex="1"></div> |
| |
| <script> |
| if (window.testRunner) |
| testRunner.dumpAsText(); |
| // .focusable still needs layout at this point, but LayoutView doesn't |
| // think any descendants need layout. |
| document.querySelector('.focusable').focus(); |
| </script> |
