css - Firefox text-overflow with nowrap ignored (Chrome works)

Question

I have created a JSFiddle with the issue here

This worked on Firefox v33 and v33.1, however has been failing in 34-35. This works in Chrome and IE11 properly. It may be a bug in Firefox, but I'm not sure. Basically I have HTML that looks like this:

.container {
  position: absolute;
  width: 150px;
}
.innercontainer {
  position: relative;
  padding-right: 25px;
  margin-bottom: 10px;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}
.outerwrapper {
  display: block;
  height: 24px;
  text-align: center;
  font-size: 10px;
  line-height: 24px;
  margin-bottom: 5px;
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  box-orient: horizontal;
  -webkit-box-orient: horizontal;
  flex-direction: normal;
  -ms-flex-direction: normal;
  -moz-flex-direction: normal;
  -webkit-flex-direction: normal;
}
.wrapper {
  flex: 1;
  -ms-flex: 1 0 auto;
  -moz-flex: 1;
  -webkit-flex: 1;
  -webkit-box-flex: 1;
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  box-orient: horizontal;
  -webkit-box-orient: horizontal;
  flex-direction: normal;
  -ms-flex-direction: normal;
  -moz-flex-direction: normal;
  -webkit-flex-direction: normal;
  background-color: grey;
}
.wrapper span {
  display: block;
  flex: 1;
  -ms-flex: 1;
  -moz-flex: 1;
  -webkit-flex: 1;
  -webkit-box-flex: 1;
  text-align: left;
  font-size: 10px;
  padding: 0 5px;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  color: #FFFFFF;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
}

<div class="container">
  <div class="innercontainer">
    <section class="outerwrapper">
      <div class="wrapper">
        <span>
          super long string in here super long string
          in here super long string in here
        </span>
      </div>
    </section>
  </div>
</div>

More efficient (and direct) than the other solution here -- just set min-width to 0.

.wrapper {
    min-width:0;
}

(This is better than overflow:hidden, because setting overflow makes the browser create a scrollable area under the hood, which has a memory cost.)

See my answer on this other question for more on why this is needed in Firefox 34. (It's from a flexbox spec change, which so far has only shipped in Firefox.)

.container {
  position: absolute;
  width: 150px;
}
.innercontainer {
  position: relative;
  padding-right: 25px;
  margin-bottom: 10px;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}
.outerwrapper {
  display: block;
  height: 24px;
  text-align: center;
  font-size: 10px;
  line-height: 24px;
  margin-bottom: 5px;
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  box-orient: horizontal;
  -webkit-box-orient: horizontal;
  flex-direction: normal;
  -ms-flex-direction: normal;
  -moz-flex-direction: normal;
  -webkit-flex-direction: normal;
}
.wrapper {
  flex: 1;
  -ms-flex: 1 0 auto;
  -moz-flex: 1;
  -webkit-flex: 1;
  -webkit-box-flex: 1;
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  box-orient: horizontal;
  -webkit-box-orient: horizontal;
  flex-direction: normal;
  -ms-flex-direction: normal;
  -moz-flex-direction: normal;
  -webkit-flex-direction: normal;
  background-color: grey;
  min-width:0;
}
.wrapper span {
  display: block;
  flex: 1;
  -ms-flex: 1;
  -moz-flex: 1;
  -webkit-flex: 1;
  -webkit-box-flex: 1;
  text-align: left;
  font-size: 10px;
  padding: 0 5px;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  color: #FFFFFF;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
}

    <section class="outerwrapper">
      <div class="wrapper">
        <span>
          super long string in here super long string
