Add 18 crash tests covering various scenarios where image loading callbacks fire after an iframe has been removed from the DOM, making its document inactive. These tests cover microtasks, element tasks, batching dispatcher callbacks, decode promises, lazy loading, srcset, picture elements, nested iframes, document adoption, and iframe reattach/remove cycles.

<!-- Test: Rapidly change image src while simultaneously removing the iframe.

Each src change queues a new microtask and increments the update counter.

Some microtasks may run after the iframe is removed. -->
