```html
<dialog id="dialog">Some Dialog Content</dialog>
<script>
dialog.showModal();
dialog.oncancel = () => {
dialog.requestClose();
};
dialog.requestClose();
</script>
```
This leads to a RangeError: Maximum call stack size exceeded. in WebKIt.
The spec prevents this through CloseWatcher machinery, we should add a guard to prevent this until CloseWatchers are finished and integrated with dialog.
