Currently, v1.6.2 the favorite-unfavorite button is within the h1 element which is incorrect. It should be outside of the h1 element.
Current markup:
<h1>
<span class="qa-favoriting" id="favoriting">
<input title="Remove this question from my favorites" name="favorite_Q_28771_0" onclick="return qa_favorite_click(this);" type="submit" value="" class="qa-unfavorite-button">
</span>
<span class="entry-title">Bug: Best answer button not showing up when loading comment field (via comment-state)</span>
</h1>
It should be:
<span class="qa-favoriting" id="favoriting">
<input title="Remove this question from my favorites" name="favorite_Q_28771_0" onclick="return qa_favorite_click(this);" type="submit" value="" class="qa-unfavorite-button">
</span>
