<h1>Components using innerHTML and splash attributes at same time</h1>

<p>
  Components behave unexpected if using <i>innerHTML</i> and <i>...attributes</i> at the same time. The attributes passed in are applied to the element defined by component (<i>tagName</i>) and are applied to the element <i>...attributes</i> is used on.<br>
  If you inspect the HTML rendered by component above you will see that class <i>foo</i> is applied to both the div defined by component and the paragraph splash attributes are used on.
</p>

<MyComponent class="foo">
  test
</MyComponent>

<p ...attributes>
	{{yield}}
