Can't prevent click on ie11

[nusson]

I have a handler that handle a tap event
and I want to prevent the click to do the action

<a href="http://www.google.ca" title="google" on-click="register:1">click here</a>
<a href="http://www.google.ca" title="google" on-tap="register:1">tap here</a>
<script>
  ractive.on('register', function(event){
    event.original.preventDefault()
    alert('YO');
    return false
  })
</script>

If i use click event, i'm not redirected to google
but I am within the tap event (on ie11)

I can confirm that on IE9, IE10 and IE11 too. Any thoughts what could be @Rich-Harris?
I'm pretty sure it worked at some point?
