### Describe the bug
When I try to preload a worker like this
```html
<link rel="modulepreload" href="/worker.js" />
```
I expect
```html
<link rel="modulepreload" href="/assets/worker-552d510d.js" />
```
But actually
```html
<link rel="modulepreload" href="data:application/javascript;base64,Y29uc29sZS5sb2coJ2hlbGxvIGZyb20gd29ya2VyJyk7DQo=" />
```
