Icon Button does not trigger form submit event

[JensRoland]

Describe the bug

<wa-icon-button> does not seem to trigger the form submit event. Adding type="submit" works for <wa-button> but not <wa-icon-button>.

To Reproduce

Steps to reproduce the behavior:

Create a page with the latest WA CSS and JS and insert a simple form:

<h3>Form</h3>
<form action="/delete" method="post" onsubmit="return confirm('Are you sure?');">
    <wa-icon-button name="trash-can" variant="regular" label="Delete"></wa-icon-button>
    <button type="submit">Delete</button>
</form>

If you click the normal 'Delete' button, the confirm prompt appears.

If you click the Icon button, nothing happens.

My workaround is to add onclick="this.parentElement.requestSubmit()" but it would be more intuitive to have the icon button behave the same as the button and wa-button.

Demo

CodePen login was borked so I could not save my Pen. It should only take a moment to reproduce with the code above though.
