| <meta name="assert" content="If there are multiple <body> elements, the |
| one that propagates `overflow` to the viewport would be the first one. |
| |
| However, the first one has `display: none`, and overflow propagation |
| can only happen when the element generates a box. Therefore, the viewport |
| shouldn't get scrollbars from the `overflow: scroll` on the first body. |
| |
| The second body doesn't propagate either, so it should be able to keep |
| `overflow: hidden` and hide its overflowing contents."> |
