<p>
 Summary: Transitioning to a route using the router service will put  default query params in the location bar when they should not be there.
</p>

<p>
Default page query param is 1.
Clicking these links for a router action (not service) will set the page query param, and will not put the default value in the URL.
</p>

<button {{action 'qpPage' 1}}>Page 1</button>
<button {{action 'qpPage' 2}}>Page 2</button>

<p>
Clicking page 1 within a component that uses the router service will put the default query param in the URL (only if you click this button first).
</p>

<p style="color: red;">Click red button first</p>
