Bug 165904 – Move charCode / keyCode / which attributes from UIEvent to KeyboardEvent

• Component: DOM
• Status: RESOLVED FIXED

[Chris Dumez]

Bring back KeyboardEvent's charCode / keyCode / which attributes.

They are still in the specification: https://w3c.github.io/uievents/#legacy-interface-KeyboardEvent
They are still exposed by Firefox and Chrome.
They are still covered by W3C web-platform-tests.
Our implementation still supports them, we merely did not expose them to the Web.

Wow, this is the only test we have to cover this functionality. Can we please add more tests?

I would have thought we’d do this instead:

    shouldBeFalse("'charCode' in xxx");

Why not test that that the property is not even present rather than testing for the weaker condition that the property’s value is undefined?
