Notice the flash. I'd expect `suspended` to be `true` during the high pri render.
if (prevState !== null) {
      if (enableSuspenseServerRenderer) {
        const dehydrated = prevState.dehydrated;
        if (dehydrated !== null) {
          if (!didSuspend) {
            return updateDehydratedSuspenseComponent(
              current,
              workInProgress,
              dehydrated,
              prevState,

            );
          } else if (
            (workInProgress.memoizedState: null | SuspenseState) !== null
          ) {
             
             
            workInProgress.child = current.child;
             
             
            workInProgress.effectTag |= DidCapture;
            return null;
          } else {
             
             
             
             
            const nextFallbackChildren = nextProps.fallback;
            const primaryChildFragment = createFiberFromFragment(
