Batched state changes are not flushed if the promise code changes the DOM (= attaching an iframe). Reproduceable with Safari.

React version: 18.1.0

## Steps To Reproduce

1. Open [codepen](https://codepen.io/kh-viewar/pen/wvpVLxM) with Safari.
2. Click "Upload"
3. => "Spinner" text does not render while Promise is in pending

## The current behavior

State changes are not executed.

## The expected behavior

State should change to true and render spinner component. After promise is resolved (2 seconds timeout), state should switch back to false and spinner component should unmount.

## Original discussion

https://github.com/facebook/react/issues/24365
newCallbackNode = scheduleCallback(
      schedulerPriorityLevel,
      performConcurrentWorkOnRoot.bind(null, root),
    );
  }
  root.callbackPriority = newCallbackPriority;
  root.callbackNode = newCallbackNode;
}
 This is the entry point for every concurrent task, i.e. anything that
 goes through Scheduler.
function performConcurrentWorkOnRoot(root, didTimeout) {
  if (enableProfilerTimer && enableProfilerNestedUpdatePhase) {
    resetNestedUpdateFlag();
  }
   Since we know we're in a React event, we can clear the current
   event time. The next update will compute a new event time.
  currentEventTime = NoTimestamp;
  currentEventTransitionLane = NoLanes;
  if ((executionContext & (RenderContext | CommitContext)) !== NoContext) {
    throw new Error('Should not already be working.');
  }
   Flush any pending passive effects before deciding which lanes to work on,
   in case they schedule additional work.
  const originalCallbackNode = root.callbackNode;
  const didFlushPassiveEffects = flushPassiveEffects();
  if (didFlushPassiveEffects) {
     
     
    if (root.callbackNode !== originalCallbackNode) {
