if (b === 'keypress') this.charCode = a.charCode || a.keyCode;

```

Looks like that `keyCode` of `keypress` events are treated correctly. Do we receive different code from the domain?

common.min.js:
```
function sn(e) {
var t = e.keyCode;
return 'charCode' in e ? 0 === (e = e.charCode) && 13 === t && (e = 13)  : e = t,
10 === e && (e = 13),
32 <= e || 13 === e ? e : 0
}
