Customer navbar pop when calling Actions.pop()

[jlafrance]

Version

Tell us which versions you are using:

• react-native-router-flux v3.39.2"
• react-native v0.44.0"

Expected behaviour

That only the scene pop out when using a custom nav bar and calling Actions.pop(), but not the custom nav bar itself.

Actual behaviour

Actions.pop() have a weird transition where I see all my screen pop from left to right (including the nav bar).

Note: the navbar is still there in the loaded scene

Description

The transition is smooth without popping or reloading the nav bar when I go from the beneficiaries scene to beneficiaryDetails by calling Actions.beneficiaryDetails(), but then the navbar pop when I call Actions.pop() from the beneficiaryDetails scene.

      <RouterWithRedux navBar={Toolbar}>
       <Scene
        key="root"
        component={connect(state => ({ active: state.tabbar.active }))(Switch)}
        tabs
        unmountScenes
        hideNavBar={false}
        selector={props => props.active}
        duration={300}
      >
        <Scene key="dashboard"
          component={dashboard}
          hideNavBar={false}
        />
        <Scene key="beneficiaries"
          component={BeneficiaryComponent}
          hideNavBar={false}
          sceneStyle={{paddingTop: 76}}
        />
        <Scene key="history" component={HistoryComponent} hideNavBar={false} />
      </Scene>
      <Scene key="beneficiaryDetails"
        component={BeneficiaryDetailComponent}
        hideNavBar={false}
        sceneStyle={{paddingTop: 76}}
        duration={300}
      />
    </RouterWithRedux>

note: seems to be related because the scene is in the tabbar root
