img element cannot properly handle "loading" attribute

Describe the bug
A clear and concise description of what the bug is.
I'm using Vue, so terms may get confused. Essentially, happy-dom doesn't set loading attribute on img to be eager or loading
To Reproduce
Steps to reproduce the behavior:

1. Set attribute loading on to be "lazy"
2. attribute loading does not become lazy

Expected behavior
A clear and concise description of what you expected to happen.
Attribute loading should become lazy

My Vue test

  it('has attr loading to be lazy when prop lazy', () => {
    const wrapper = mount(BImg, {
      props: {lazy: true},
    })
    expect(wrapper.attributes('loading')).toBe('lazy')
  })

  it('has attr loading to be eager when prop lazy false', () => {
    const wrapper = mount(BImg, {
      props: {lazy: false},
    })
    expect(wrapper.attributes('loading')).toBe('eager')
  })

  it('has attr loading to be eager by default', () => {
    const wrapper = mount(BImg)
    expect(wrapper.attributes('loading')).toBe('eager') // In my code prop loading is undefined === prop loading is false
  })

When using happy-dom, all of these "loading" attributes become undefined. Lazy on becomes loading="lazy", lazy off becomes loading="eager". Neither are made
