无法使navContainer适用于微型滑块（VUE）

Question

我正在尝试使navContainer正常工作，但无法使用Vue版本的微型滑块。我也尝试过为此选项

-navContainer: '#customize-thumbnails'，
-navContainer: document.querySelector('#customize-thumbnails')，
-navContainer: this.$refs.sliderThumbs，

 它什么也没做。我可能会缺少什么？

<tiny-slider ref="tinySlider" v-bind="tinySliderOptions" class="customize" id="customize">
