title: saving a dash layout to html file
body: <p>I plotted a bunch of things in a dash layout. I want to save them to an html file so I can look at them later. when I reopen the saved html file, I first see everything correctly. However, within &lt;2s, the page goes blank and I get an error: “Error loading layout”.</p>
  
  <p>How can this be fixed?</p>
  
  <p>Thanks!</p>
