Can't render multiple controls without wrapping them in a container

Describe the bug

The following code should render two controls (as shown in the documentation), however no controls are rendered.

<template #controls>
    <!-- no controls are rendered -->
    <HstSelect title="Color" v-model="state.color" :options="colors" />
    <HstText title="Label" v-model="state.label" />
</template>

Wrapping both controls inside a container solves the issue:

<template #controls>
    <!-- two controls are rendered -->
    <div>
        <HstSelect title="Color" v-model="state.color" :options="colors" />
        <HstText title="Label" v-model="state.label" />
    </div>
</template>

I provided a Nuxt Stackblitz reproduction, with two <Variant>s of <BaseButton>, reproducing the bug.
