Incorrect HTML string generated

[fabiospampinato]

Describe the bug

There's a mismatch between what I get with HappyDOM, and what I get with LinkedDOM or the actual DOM, so I'm pretty sure there's some bug in HappyDOM somewhere.

To Reproduce

1. cd into this folder https://github.com/vobyjs/voby/tree/master/demo/ssr_esbuild
2. npm install
3. Put this console.log(document.getElementById ( 'app' ).innerHTML) here, to log the HTML generated.
4. npm dev
5. Go to http:/localhost:3000/counter
6. Notice how there's a 0 below the <h1>Counter</h1>, as expected.
7. npm install happy-dom-global.
8. Replace linkedom-global for happy-dom-global here.
9. Go to http:/localhost:3000/counter and notice how the logged HTML doesn't have a 0 anymore. You'll still see one in the page because the page is re-rendered client-side, to turn that off comment out this line.

Expected behavior

HappyDOM's output should make LinkeDOM's and the browser's.

Additional context

I'm not exactly sure what the issue is, the only thing I can think of is that calling .nodeValue = 0 maybe doesn't work in Happy DOM, if that's not the issue I'm not sure what it is.
