Hi, I have the same issue with SSR.

When I use <client-only></client-only> this resolve the error but I want use SSR.

It's possible to add in src/vue-horizontal.vue a '?' for prevent this error ?

    children(): HTMLCollection {
      const container = this.$refs.container as Element
      return container?.children ?? []
    },
