Wrong select value when option with empty value is selected

[modiho]

Describe the bug

A select element reports the text content of an option that has an empty value as its value, instead of the empty string.

To Reproduce

Execute the following in a Node.js repl:

let {GlobalRegistrator} = require('@happy-dom/global-registrator')

GlobalRegistrator.register();

document.body.innerHTML = `<form>
  <select name="size">
    <option value="">Please choose</option>
    <option value="s">S</option>
    <option value="m">M</option>
  </select>
</form>`

document.querySelector('select').value // => "Please choose"

Expected behavior

document.querySelector('select').value // => "" (empty string)

Screenshots

Device:

• Node.js v18.14.1, happy-dom v12.9.1

Additional context

In a browser or JSDom, this works as expected.
