title: Increasing the background-size in CSS makes the background image disappear
body: <p>this is what I have:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.slot {
    border: 1px solid;
    border-color: rgba(90, 90, 90, 1);
    height: 31px;
    background: url(https://i.imgur.com/r6ihXJe.png), rgba(150, 150, 150, 1);
    background-position-x: center !important;
    background-repeat: repeat-y, no-repeat !important;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="slot" style="width:345px; background-size: 62px, auto;"&gt;&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>This is the result:</p>
  
  <p><a href="https://i.stack.imgur.com/cXAjC.png" rel="nofollow noreferrer">slot with bg image</a></p>
  
  <p>Now the issue comes when the background-size property changes to more than 62px. For example when it becomes 63px and more - the background image disappears:</p>
  
  <p><a href="https://i.stack.imgur.com/Dicwf.png" rel="nofollow noreferrer">slot with no bg image</a></p>
  
  <p>Interesting that if we increase the height of the div then we can have a bigger background-size and still see the background image.</p>
  
  <p>Here is a jsFiddle I made: <a href="https://jsfiddle.net/avc4y3h0/" rel="nofollow noreferrer">https://jsfiddle.net/avc4y3h0/</a></p>
  
  <p>Please help!</p>
  
  <p><strong>Edit:</strong> It seems that I can reproduce this issue only on Google Chrome, Avast Browser and Opera. It works fine on Mozilla Firefox and Microsoft Edge. Can not check on Safari. Also I have the feeling that this was working before on Chrome and it is probably something recent? But I can't tell for sure.</p>
