userEvent.keyboard(']') results in {key: ']', code: 'Unknown'}

[bryan-codaio]

Reproduction example

https://codesandbox.io/p/sandbox/festive-rhodes-5mpcfy?file=%2Fsrc%2FApp.js%3A11%2C27

Prerequisites

1. Create a test with an onKeyDown event handler (e.g. with an <input onKeyDown={(e) => console.log(e.code)} /> element)
2. Create a test w/ userEvent.type(inputElement, ']');

Expected behavior

The KeyboardEvent.code value ought to be 'BracketRight' same as if it were done in a browser (tested in chrome 125)

Actual behavior

The KeyboardEvent.code value is 'Unknown' per this fallback logic:

user-event/src/keyboard/parseKeyDef.ts

Line 41 in d036279

code: 'Unknown',

User-event version

14.5.1

Additional context

I imagine the fix is a relatively simple addition to https://github.com/testing-library/user-event/blob/main/src/keyboard/keyMap.ts, but perhaps I'm missing some context
