Err the Fail and Pass snippets have the same code, could you edit them to be different please? I'm not following what this is asking for otherwise.

Well to be honest there aren't fail and pass snippets.
When accessing KeyboareEvent.keyCode the keyCode is a deprecated property.
Currently there is no way to allow the keyCode property using the options of the rule.

Anything else missing?

For example maybe something like this:

{
  "allow": [
    { "from": "lib", "name": "KeydownEvent.keyCode" }
    // Or maybe
    { "from": "lib", "name": "KeydownEvent", "property": "keyCode" }
  ]
}

Oh gotcha, thanks. That is interesting. I can see why you'd want this. 👍 from me on trying to find a good solution here.

This also seems related to #10740. Both of these issues are about expanding TypeOrValueSpecifier to target properties.

I'll go ahead and mark this as a duplicate, quote the reasoning here, and push that conversation forward a bit. Thanks for filing!
