Summary [Site Isolation] Fix editing/selection/drag-in-iframe.html

The test wants to snapshot a drag mid-gesture: it calls notifyDone() before the trailing mouseUp() so the dump captures the drag caret. Without site isolation that works because notifyDone() is synchronous. With site isolation it's async, so the mouseUp() runs first, the drop completes, and the snapshot reflects post-drop DOM. I switched the mouse calls to the async eventSender APIs and dropped the trailing mouseUp() — it was only cleanup, and it's the actual failure under site isolation. I also removed the now-passing expectation.
