Summary requestClose() on a disconnected dialog removes open attribute

Per the spec requestClose() should early return if the dialog it's called on is disconnected, or it's document is inactive. `data:text/html,<script>const dialog = document.createElement('dialog'); dialog.setAttribute('open', ''); dialog.requestClose(); alert(dialog.open);</script>` This should alert with true like in Chromium and Firefox.
