CSS text-overflow ellipsis not working

Question

I'm not sure why this basic CSS isn't functioning...

.app a {
  height: 18px;
  width: 140px;
  padding: 0;
  overflow: hidden;
  position: relative;
  margin: 0 5px 0 5px;
  text-align: center;
  text-decoration: none;
  text-overflow: ellipsis;
  white-space: nowrap;
  color: #000;
}

<div class="app">
  <a href="">Test Test Test Test Test Test</a>
</div>

So, if you've arrived at this question because you're having difficulties getting the ellipsis to operate inside a display: Try adding min-width: 0 to the outmost container that's overflowing its parent, even if you've previously set overflow: hidden to it, and see how it works for you.
