path-deps: Cannot set properties of undefined (setting 'PathDeps')

I'm using Vite. In development mode it works fine. But somethings going wrong when budling.:

`Uncaught TypeError: Cannot set properties of undefined (setting 'PathDeps')`

The debug extension is working fine.

htmx.js
```
import htmx from 'htmx.org';
window.htmx = htmx;
```

main.js
```
import './htmx.js';
import 'htmx-ext-path-deps';
import "htmx-ext-debug";
import "htmx-ext-alpine-morph";
...
```

vite.config.js
```
plugins: [
inject({
htmx: 'htmx.org',
}),
...
```

Read htmx.js, main.js, and vite.config.js together, then reproduce the production bundle with the shown imports and inject configuration. Trace where htmx-ext-path-deps assigns PathDeps and compare that with the available htmx object; done means the bundle no longer throws this error and the extension works in the bundled application.
