bug: Warning: Unknown event handler property `onIonTabsWillChange`. It will be ignored.

I got a warning but it works.

  return (
    <IonTabs onIonTabsWillChange={(e) => onChange(e.detail.tab)}>
      <IonRouterOutlet>
        {tabNames.map((tab) => (
          <Route key={tab} path={`/${tab}`} render={() => <></>} />
        ))}
      </IonRouterOutlet>
      <IonTabBar
        style={{ heigth: "56px" }}
        slot="bottom"
        selectedTab={selected}
      >
        {children}
      </IonTabBar>
    </IonTabs>
  );
