Unable to load js file: "Missing end of curly braces on line 4 and column 2560"

Hi thanks for happy-dom. I'm developing a plugin for datastar and I'm looking to use happy-dom to run some integration tests. I want to make sure my data plugin behaves how it's expected to behave when it's running alongside datastar in the browser.

I'm having an issue loading datastar.js using happy-dom. I tried datastar v1.0.0-RC.6 and v1.0.0-RC.7. and I saw similar errors, Missing end of curly braces on line ... I don't know if this is an issue with datastar or an issue with happy-dom, so I'm starting a discussion to see if the community has any insight.

I've created a MVR https://github.com/insanity54/happydom-issue with a test file to demonstrate the issue. https://github.com/insanity54/happydom-issue/blob/main/test/loader.test.ts

The test also loads nanoid, a widely used npm package for generating ids. I did this to confirm if I was using happy-dom correctly (I'm brand new to the library), and compare with how I am loading datastar.

I'm not sure what's going on with the error during loading datastar. I have only theories.

1. I'm loading the file incorrectly
2. Datastar's bundle contains quirks that happy-dom cannot parse. (It is a very quirky library so I would not be surprised)
3. Something else is happening that I haven't thought of

I'm hoping I can get to the bottom of this. Thanks for taking a look.
