:initial style is not applied during SSG build - Vitesse

Here's repro: https://github.com/Idered/vitesse-motion-ssg-bug

```vue
  <div
    v-motion
    :initial="{
      opacity: 0,
      y: 100,
    }"
    :enter="{
      opacity: 1,
      y: 0,
    }"
  >
    Motion
  </div>
```
is compiled to 

```vue
<div>Motion</div>
```
but it should be
```vue
<div style="opacity: 0; transform: translateY(100px);">Motion</div>
```
