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

Link to code example:

https://codepen.io/kh-viewar/pen/wvpVLxM

## 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.

logRenderStopped();
    }
  }
  if (enableSchedulingProfiler) {
    markRenderStopped();
  }
   
  workInProgressRoot = null;
  workInProgressRootRenderLanes = NoLanes;
  return workInProgressRootExitStatus;
}
 The work loop is an extremely hot path. Tell Closure not to inline it.
/** @noinline */
function workLoopSync() {
   
  while (workInProgress !== null) {
    performUnitOfWork(workInProgress);
  }
}
function renderRootConcurrent(root: FiberRoot, lanes: Lanes) {
  const prevExecutionContext = executionContext;
  executionContext |= RenderContext;
  const prevDispatcher = pushDispatcher();
   
   
  if (workInProgressRoot !== root || workInProgressRootRenderLanes !== lanes) {
    if (enableUpdaterTracking) {
      if (isDevToolsPresent) {
        const memoizedUpdaters = root.memoizedUpdaters;
