<h3 dir="auto">Steps to reproduce</h3>
<ul dir="auto">
<li>Note the component emits an $event along with an extra argument string</li>
<li>Click the "no prevent" button</li>
<li>Note that the message is passed and is displayed</li>
<li>Click the "has prevent" button</li>
<li>Note that the message is undefined and clears the display</li>
</ul>
<p dir="auto">Both buttons also log to the console for more detailed output.</p>
<h3 dir="auto">What is expected?</h3>
<p dir="auto">Additional arguments would be passed when event modifiers are used.</p>

<p dir="auto">Additional arguments are being ignored/removed.</p>
