title: Safari media-queries print not using height 100% correctly
body: <p>I'm using printing media queries for an app that is working fine on Chrome/Edge/Firefox but is failing on Safari. I'm using  height 100% in order to make it fill the printing page, on safari it seems to be using the percentages as a percentage of the element itself. I have put simplified code below.</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;title&gt;print test&lt;/title&gt;
  &lt;/head&gt;
  &lt;style&gt;
      .big{
          border:5px solid black;
      }
      @media print {
          .breaker{
              page-break-before: always;
          }
          .big{
              display:block;
              position:  relative;
              height:100%;
          }
      }
  &lt;/style&gt;
  &lt;body&gt;
      &lt;svg class = "big" width="700px" height="1000px"&gt;&lt;/svg&gt;
      &lt;div class = "breaker"&gt;&lt;/div&gt;
      &lt;svg class = "big" width="700px" height="1000px"&gt;&lt;/svg&gt;
      &lt;div class = "breaker"&gt;&lt;/div&gt;
      &lt;svg class = "big" width="700px" height="1000px"&gt;&lt;/svg&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
