title: Next.js links refresh the page
body: <p>I have a Next.js blog with only 2 routes: <code>/</code> and <code>/posts/:slug</code>.</p>
  
  <p>When I'm on <code>/posts/my-post-title</code>, and I click on the back link (to <code>/</code>), all is fine. The page loads fast (no refresh).</p>
  
  <p>When I'm on <code>/</code>, and I click on <code>/posts/my-post-title</code>, the page refreshes and I can't figure out why. Any suggestion?</p>
