Highlighting bug with edgegrams

In 3.5.0 we have the following.

    <fieldType name="autocomplete" class="solr.TextField"
positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="30"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
    </fieldType>

If we searched for "c" with highlighting enabled we would get back
results such as:

<em>c</em>dat
<em>c</em>rocdile
<em>c<e/m>ool beans

But in the latest Solr (4.7.1) we get the full words highlighted back.
Did something change from these versions with regards to highlighting?

Thanks
