Indicator is not shown when it has PagerItems defined, the property showIndicator is true

When defining PagerItems as Pager content, the indicator is not shown (showIndicator is set true)

      <Label text="Home"/>
    </ActionBar>
    <GridLayout height="300" width="100%" backgroundColor="white">
      <Pager
        height="250"
        width="100%"
        orientation="horizontal"
        :selectedIndex="selectedIndex"

        <PagerItem v-for="(item, i) in items" :key="i">
         <GridLayout height="100%" :backgroundColor="item.color" opacity="0.5">
            <Label verticalAlignment="top" :text="item.title" />
            <Button  verticalAlignment="middle" @tap="onTap" :text="'Click ' + item.title" />
          </GridLayout> 
        </PagerItem>
      </Pager>
    </GridLayout>
  </Page>
</template>
<script lang="ts">
  import Vue from "nativescript-vue"

  export default Vue.extend({
     data() {
      return {
        items: [
          { title: 'First', color: '#e67e22' },
          { title: 'Second', color: '#3498db' },

          { title: 'Fourth', color: '#9b59b6' },
        ],
        selectedIndex: 0,
      }
    },
    methods: {
      onTap() {
        console.log('***********************On tapped')
      },
      onSelectedIndexChanged(args: { value:number }){
        this.selectedIndex = args.value;
      },
    }
  });
</script>```

Start by reproducing the provided NativeScript-Vue example with PagerItems, showIndicator="true", and the listed dependencies. Trace the Pager and PagerItem indicator handling, then verify that the indicator appears for the four-item example without changing the reported configuration.
