Object.keys(localStorage) returns ['_store'] not the keys stored

[knownasilya]

Describe the bug
Object.keys(localStorage) returns ['_store'] not the keys stored
You have to do Object.keys(localStorage._store) to get the keys.
This also happens with for-in loop.

Using "happy-dom": "^12.10.3"

To Reproduce
Steps to reproduce the behavior:

1. Set values on localStorage
2. Run Object.keys(localStorage)
3. See incorrect result

Expected behavior
Object.keys(localStorage) should return keys that were set.

Device:

• OS: macos m1 latest version

Workaround:

for (let i = 0; i < localStorage.length; i++) {
    const key = localStorage.key(i);
    // access each key
}

I encountered the same situation as you, after emulating the storage of a value, I used Object.keys(window.localStorage) to get an empty array.
