Notice the flash. I'd expect `suspended` to be `true` during the high pri render.
if (current === null) {
     
     
    if (nextProps.fallback !== undefined) {
      tryToClaimNextHydratableInstance(workInProgress);
       
      if (enableSuspenseServerRenderer) {
        const suspenseState: null | SuspenseState =
          workInProgress.memoizedState;
        if (suspenseState !== null) {
          const dehydrated = suspenseState.dehydrated;
          if (dehydrated !== null) {
            return mountDehydratedSuspenseComponent(
              workInProgress,
              dehydrated,
              renderExpirationTime,
