Tool tip with drag mode doesn't work in single slider

[shynline]

To clarify it does work for multi-handle slider

<Slider :min="0"
        :max="100"
        :step="1"
        :tooltips="true"
        showTooltip="drag"
        v-model="value"
        :classes="sliderClass" />
 // sliderClass: same as provided in README

const value = ref([20, 60]) // Tooltip on drag works
const value = ref(14)       // Tooltip on drag doesn't work
