paper-input type="number" input events missing

[jscissr]

Description

On <paper-input type="number"></paper-input> elements, the input event does not fire when using the arrow buttons:

The reason is that the input events from the keyboard have composed: true, but the input events from the arrow buttons have composed: false; which means that these events don't bubble out of Shadow DOM.

I'm not sure, maybe this is a bug in Chrome and the event should also be composed. But if it is intended behavior in Chrome, it might be necessary to forward the input event in paper-input, like the change event.
