+1 Button Generator Bug
While changing the code for my +1 button to use the recently announced +Snippets, I noticed that the +1 Button Generator is outputting invalid syntax when using HTML5 and specifying a URL.
The generator currently outputs something like:
<div class=g-plusone data-annotation=inline href="http://foo.com"></div>
When the correct syntax should be:
<div class=g-plusone data-annotation=inline data-href="http://foo.com"></div>
Took me a while to figure out what was going on.
I've reported the problem on the Webmaster Central forum.
