title: Sapper loading pages underneath each other
body: <p>I have a sapper/svelte app that when I navigate from my profile page to another page (let's say home) the home page loads underneath the profile page for a split second. Then loads normally.</p>
  
  <p>Before clicking to go home:</p>
  
  <p><a href="https://i.stack.imgur.com/pkXDv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pkXDv.png" alt="enter image description here"></a></p>
  
  <p>After clicking home page link: 
  <a href="https://i.stack.imgur.com/3Qp0g.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3Qp0g.png" alt="enter image description here"></a></p>
  
  <p>This is crazy to me and I have no idea whats going on?? </p>
  
  <p>After a split second, the profile page disappears and the home page displays correctly.</p>
