flexbox | flex item being pushed out of containing div (off screen)

Question

I'm using the flexbox layout to style a list of past tasks. The task description and the time are always going to be of very variable lengths.

Everything looks great until a task description is entered which is long enough to wrap onto a second line and then the 'time' item (on the far right of the screen) is pushed slightly to the right - off the screen - hiding some of the content.

You can see the short description displays perfectly below, but the long one pushes what should be '00:08' off the screen AND the task description moves to the left as well!!

Here's a fiddle for the code (which is below as per Stackoverflow's rules). If you resize the pane containing the result the '00:08' doesn't fall off the page but it does clearly move too far to the right.

The above screenshot is in Chrome or Safari (the two browsers I was using) when shrinking the width of the window until the description wraps onto a second line.

I would like everything to display as per the first (short description) line if possible! And also to understand why this is behaving as it currently is.

P.S. I have tried using floats and also using a table display layout but both of these techniques caused quite a few bugs, mostly because of the variable length content (so please don't suggest these as alternatives :)).

ul {
      margin:0;
      padding: 0;
    }
    #tasklist{
      width: 100%;
    }
    
      .task-one-line{
        display: flex;
        flex-direction:row;
        flex-wrap: nowrap;
        justify-content: space-between;
        align-item: baseline; /*flex-end*/

      }
    
        .task-one-line i{
          width:1.5em;
          padding: 0.5em 0.3em 0.5em 0.3em;
          /*border: 1px solid green;*/
        }
    
          span.task-desc{
            flex-grow: 5;
            -webkit-flex-grow: 5;
            text-align:left;

          }

I had a similar issue, I created a pen with the fix:

https://codepen.io/anon/pen/vRBMMm

.flex {
  display: flex;
  padding: 8px;
  border: 1px solid;
}

.a {
  margin-right: 16px;
}

.b {
  flex: 1;
  background: #ffbaba;
  min-width: 0;
  white-space: nowrap;
  text-overflow: ellipsis;
  overflow: hidden;
}

.c {
  flex-shrink: 0;
  margin-left: 16px;
}

<div class="flex">
  <div class="a">1st div</div> 
  <div class="b">HELLO2HELLO2 HELLO2HELLO2 2222 HELLO2HELLO 22222</div>
  <div class="c">3rd div</div>
</div>

Really, you only want the text content to have a flexible width (the time and the icon should have a fixed width and not shrink). This could be pretty easily accomplished with tables, absolute positioning, or flexbox.

Here's the flexbox that you need to know:

.task-time: flex: 1 0 4em
.task-one-line i.fa { flex: 0 0 auto; }

ul {
      margin:0;
      padding: 0;
    }
    #tasklist{
      width: 100%;
    }
    
      .task-one-line i.fa { flex: 0 0 auto; }
      .task-one-line{
        display: flex;
        flex-direction:row;
        flex-wrap: nowrap;
        justify-content: space-between;
        align-item: baseline; /*flex-end*/
        display: -webkit-flex;
        -webkit-flex-direction:row;
        -webkit-flex-wrap: nowrap;
        -webkit-justify-content: space-between;
        -webkit-align-item: baseline; 
        border-bottom: 1px solid #d3d3d3;
        width: 100%;
      }
    
        .task-one-line i{
          width:1.5em;
          padding: 0.5em 0.3em 0.5em 0.3em;
          /*border: 1px solid green;*/
        }
    
          span.task-desc{
            flex-grow: 5;
            -webkit-flex-grow: 5;
            text-align:left;
            padding: 0.3em 0.4em 0.3em 0.4em;
            /*border: 1px solid red;*/
          }
         
          span.task-time{
            flex: 1 0 4em;
            -webkit-flex: 1 0 4em;
            text-align:right;
            padding: 0.3em 0.5em 0.3em 0.5em;
            /*border: 1px solid blue  ;*/
          }

<ul id="tasklist">
        <li class="task-one-line">
            <i class="fa fa-check-circle-o"></i>
            <span class="task-desc">And a short one</span>
            <span class="task-time">00:01</span>
        </li>
        <li class="task-one-line">
            <i class="fa fa-check-circle-o"></i>
            <span class="task-desc">Here's a super long long long long long long description that might wrap onto another line  long long long long long long description that might wrap onto another line</span>
            <span class="task-time">00:08</span>

    </ul>

My general rule for flex is flex the containers you want to flex and don't flex the ones you do not. I would do the following to the time container.

span.task-time {flex: none;}
