Firefox ignores padding when using overflow:scroll

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>

Did I missed something or is there any kind of work around for this issue?

Notice: the demo doesn't use any library for normalizing, but I tried normalize.css too, but without success.

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

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

Fiddle

in Firefox padding-bottom is ignored with overflow:auto or overflow:scroll, see the documentation

https://bugzilla.mozilla.org/show_bug.cgi?id=748518

still if you want to work around your example to achieve the desired result then see the fiddle: https://jsfiddle.net/nileshmahaja/4vuaf4o3/1/

Modified CSS

.container {
    height: 200px;
    padding: 50px 50px 0;
    border: solid 1px red;
    overflow-y:auto;
    display:block;
}
ul{
    padding:0 0 50px;
    display:block
}
li {
    padding: 0;
    margin: 0;
}

I'm not a fan of creating additional DOM elements to work around displaying issues, however it seems to help to split up the element into two elements like:

<div class="container">
    <div class="container-inner">
        <!-- long content -->
    </div>
</div>

and then assigning overflow: scroll to the outer element and add padding: /* ... */ to the inner element.

I ended up achieving the same effect (space between last item in a scrollable container and the end of container) in a slightly different way:

.container :last-child {
    margin-bottom: 50px;
}

Perhaps there are technical differences between what's really going on, but I find this pretty effective.
