Cannot load HTML when filename contains non-ASCII characters and with module `<script>`

### Describe the bug

I started a very basic Vite project, with a link to another HTML. But when the linked HTML filename contains non-ASCII, this error will occur on loading: `htmlProxyMap.get(...).get(...) is undefined`

### Reproduction

https://stackblitz.com/edit/vitejs-vite-q7zxua?file=index.html

### Steps to reproduce

- Open the reproduction link
- Click `á` button
- Error shows

You can notice there are three HTML files: `a` and `á` have the exactly same content, but plain `a` can be loaded successfully, the acute one can't be. `á2` also has the same content except using `<script>` instead of `<script type="module">`, and it can be loaded as well.
