title: Custom editor styles are not loading in my live WordPress site
body: <p>I have attempted to use the following code block inside my functions.php file to add some custom styling to the post editor.</p>
  <pre><code>add_theme_support('editor-styles');
  
  function load_editor_styles() {
      add_editor_style('https://fonts.googleapis.com/css2?family=Libre+Baskerville&amp;family=Montserrat:wght@300;400;500&amp;display=swap');
  
      add_editor_style(get_template_directory_uri().'/editor-style.css');
  }
  add_action('after_setup_theme', 'load_editor_styles');
  </code></pre>
  <p>The problem I'm having is that these styles will load properly on my local developer environment. But as soon as I upload my theme to my live site, the styles are no longer there.</p>
  <p>For reference, this is the compiled css for the editor-style.css:</p>
  <pre><code>h1, h2, h3, h4, h5, h6 {
    font-family: &quot;Libre Baskerville&quot;;
  }
  
  h1 {
    font-size: 30pt;
  }
  
  h2 {
    font-size: 24pt;
  }
  
  h3 {
    font-size: 22pt;
  }
  
  h4 {
    font-size: 18pt;
  }
  
  h5 {
    font-size: 14pt;
  }
  
  h6 {
    font-size: 12pt;
  }
  
  p, li, figcaption {
    color: #2e2e2e;
    font-family: &quot;Montserrat&quot;;
    font-size: 10pt;
  }
  
  h1, h2, h3, h4, h5, h6, .editor-post-title__input {
    color: #2e2e2e;
    font-family: &quot;Libre Baskerville&quot;;
  }
  
  figcaption {
    font-style: italic;
  }
  
  .editor-post-title__input {
    font-size: 32pt;
  }
  </code></pre>
  <p>WordPress version on my live site: 5.8.2</p>
  <p>Edit (#1 29 Nov 21): WordPress version on my local developer environment is also 5.8.2</p>
