Q2A version: 1.8.3
If a post has got a negative score, its itemprop upvoteCount used for Schema.org microdata will be incorrect and will contain an absolute value of the actual score.
Eg. a post with score -2 results in the following HTML:
<span class="qa-netvote-count-data">–2</span> <span class="qa-netvote-count-pad"> votes <meta itemprop="upvoteCount" content="2"> </span>
