VDropdown component errors using Browser installation: `TypeError: can't access property "offset", m is undefined`

Going off of the Browser installation: https://floating-vue.starpad.dev/guide/installation#browser

Minimum reproducible example:

```html

const { createApp } = Vue;

const app = createApp({});

app.use(FloatingVue);

app.mount('#app');

```

Console reports an error when you click the button:

```
Uncaught (in promise) TypeError: can't access property "offset", m is undefined
$_computePosition https://unpkg.com/floating-vue@^2.0.0-beta.1:1
```

Maybe I missed something 🤷‍♂️
