title: Wrong margin-top after editing wordpress page
body: <p>I have a wordpress website. After I edit any page in wordpress, a space between top of browser and menu becomes bigger. After I clean cash, the margin-top is good. It happens only in Safari (for desktop, in mobile Safari everything is good). </p>
  
  <pre><code>body {
      color: #000000;
      font-family: 'IBM Plex Mono', monospace;
      font-weight: 400;
      background-color: #fafafa;
      text-align: left;
      margin: 12px 12px 0px 12px;
      font-size: 11.5px;
      -ms-hyphens: auto;
      -webkit-hyphens: auto;
      -moz-hyphens: auto;
      hyphens: auto;
    }
  
  \\menu
  .main-navigation {
      position:fixed;
      z-index: 999;
      font-size: 100%;
      -webkit-text-size-adjust: 100%;
      -ms-text-size-adjust: 100%;
      padding-right: 12px;
    }
  </code></pre>
  
  <p>I use media queries for different displays.
  After the menu I have display:none sentence between <p></p> which is shown only on mobile devices.</p>
