css - Firefox ignores padding when using overflow:scroll

Question

When using overflow: scroll combined with padding: /* ... */ CSS property, the padding at the bottom of the element is missing in Firefox. (But works in Chrome and Safari.)

.container {
  height: 100px;
  padding: 50px;
  border: solid 1px red;
  overflow-y: scroll;
}

ul,
li {
  padding: 0;
  margin: 0;
}

<div class="container">
  <ul>
    <li>padding above first line in every Browser</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>content</li>
    <li>no padding after last line in Firefox</li>
  </ul>
</div>

Answer 1

After a bit of brainstorming with fellow developers, although not very graceful, this pure css solution works:

.container:after {
    content: "";
    height: 50px;
    display: block;
}
