When a post has a flag on it, moderators see this semi-transparent bar with details of the flag on it. One of the things the bar lists is "viewed by", listing all the mods who have seen the flag.
Now, the list of mods is a list of gravatars. In these, the URLs have HTML-encoded
&s in the query string.
So, we get gravatars like
http://www.gravatar.com/avatar/86f4f64980b4736b1f6e5e3056d08e15?s=24&d=identicon&r=PG, when we expect
http://www.gravatar.com/avatar/86f4f64980b4736b1f6e5e3056d08e15?s=24d=identicon&r=PG. (Copt them to the address bar, I can't link them mere because the SE markdown editor automagically converts the entities to ampersands in the links).
Could this be fixed?
(Btw, for some reason, an HTML-encoded URL works with half the gravatars, like mine
http://www.gravatar.com/avatar/0a3069491bfded90cdf623341cadc1d1?s=24&d=identicon&r=PG. But that's a quirk on Gravatar's side. )
