I brought this up about 4 months ago on Stack Overflow Meta, but because this problem is not only on Stack Overflow, but all other Stack Exchange sites, I'll post it again here.
Thanks to tbodt, the correct fix was found, but it still hasn't taken effect. Obviously this isn't a high priority, but seeing as it's fairly easy to fix (and the code was fixed by tbodt), why not fix it now?
Here's the post
I just noticed while upvoting a comment today, that right after it is upvoted, the color of the cool
comment score became black:
but, once I refreshed the page, and from then on, it became grey:
I also noticed that the HTML for the comment score that was initially upvoted (the non-colored one) was:
<td class=" comment-score">
<span title="number of 'useful comment' votes received" class>1</span>
</td>
Whereas the HTML for the comment score after the page was refreshed is:
<td class=" comment-score">
<span title="number of 'useful comment' votes received" class="cool">1</span>
</td>
This only happens on cool
comments (ones with score < 5), and on all Stack Exchange websites.
