Subject: [PATCH] fix: handle additional args in components' with event
 modifiers

Additional args are not passed to the component's events with modifiers.
with a component template like this
`<input @keyup="$emit('my-keyup', $event, var1, var2)"/>`
triggering the event, e.g.
`<my-component @my-keyup.enter="onMyKeyup"/>`
the `onMyKeyup` receives the `$event`, but not `var1` and `var2`

hope this PR resolves the issue.
