If preventDuplicate is enabled, calling closeSnackbar and then calling enqueueSnackbar again during the close animation will be ignored.

Expected Behavior

Displayed if enqueueSnackbar is called last when preventDuplicate is enabled.

Current Behavior

Not displayed even if enqueueSnackbar is called last when preventDuplicate is enabled.

      const key = enqueueSnackbar(button.message, { variant: button.variant });
      closeSnackbar(key);
      setTimeout(() => {
        // I want it to be displayed but ignored.
        enqueueSnackbar(button.message, { variant: button.variant });
      }, 100);

1. click button

Context

I have a component that uses React.useEffect to keep showing the snackbar as long as the component is mounted, but it no longer works with React 18 + StrictMode. Only developer mode is affected, but I would like to fix it.
