title: angular google maps v2.0.1 markers directive label will not display when hovered over
body: <p>In 1.2.x I used to set this in the options attribute. That still works for the marker directive but in 2.x that does not work for the markers (plural) directive. I tried using the labelContent (code snippet) and it didn't work either.</p>
  
  <pre><code>  &lt;ui-gmap-markers models="SelectedHotels" idkey="'id'" coords="'self'" icon="'markerIcon'" click="'onClick'" dorebuildall="true" labelContent="'officeName'"
          labelVisible="true"&gt;
      &lt;/ui-gmap-markers&gt;
  </code></pre>
  
  <p>You can see it in this plunker. The 2 right markers are the ones I'm targeting. The marker on the left is the single directive and the hover works on that one.  <a href="http://plnkr.co/edit/4eF1Wu4tURysTji0b5kO?p=preview" rel="nofollow">http://plnkr.co/edit/4eF1Wu4tURysTji0b5kO?p=preview</a></p>
