[Why] is this the only place this is necessary?

I'd like to start here and expand as necessary.
I'll move the class if it is used in 2+ places.
I created a bug to track the question with Alan
about what should/shouldn't elide or wrap.

https://bugs.chromium.org/p/chromium/issues/detail?id=619670

         <div class="text-elide">[[model.title]]</div>
         <div class="text-elide secondary">[[model.url]]</div>
       </div>
