userEvent.type backspace does not work

[lanmonster]

• @testing-library/user-event version: "^12.1.10"

• Testing Framework and version: it's a default CRA project and react-scripts is version 4.0.1. not sure what version of jest it uses...
• DOM Environment: jsdom "@testing-library/jest-dom": "^5.11.4",

Relevant code or config

it('test', () => {
    render(<App />)

    userEvent.type(document.body, "{backspace}")

    //error
})

What you did: trying to test behavior when backspace is pressed

What happened: backspace event is not fired and there is an error saying "cannot read length of undefined"

Reproduction repository:

Problem description: backspace event does not appear to fire

Suggested solution: 🤷

Thanks for the report :)

Duplicate of #481 .

Will be fixed with #521, but I guess this will take some time.
Until then, you can not use userEvent.type to type on non-editable elements.
