Keyboard events created with DOM don't trigger

There is a [known bug with Webkit](https://bugs.webkit.org/show_bug.cgi?id=16735) where KeyboardEvents created by the DOM have keyCode and charCode of 0, thus preventing us from manually triggering 'change' or 'input' events with this library.

I have managed to create a workaround by triggering a 'blur' Event on the input, but ultimately triggering the KeyboardEvent with a Tab or Comma would have been a better way of interacting.

Native JavaScript, particularly JS packages, is not my forte but I'm sure a simple solution to this issue would be to modify the event listeners to work off Keys rather than KeyCodes.

Empieza reproduciendo el comportamiento de WebKit descrito en el issue: los KeyboardEvents creados por el DOM tienen keyCode y charCode establecidos en 0. Revisa los event listeners de la biblioteca e investiga si pueden usar keys en lugar de key codes; después, verifica que Tab o Comma puedan activar el comportamiento de entrada o cambio previsto sin depender de blur.
