For a couple years now, we've had support for furigana on JLU. It always worked pretty well, and although there've been a couple small issues, we've been able to work around them.
Right now, though, furigana appears not to work at all! For example, see this answer which is supposed to be loaded with furigana. The text between {} should appear above the text between [] that comes immediately before it.
Instead, it's as if the furigana script is not run at all. We see the brackets and the text appears between those brackets. The same has been true in every question I've looked at with furigana, both on the main site and meta, in answers and in comments.
It appears to be broken in multiple browsers. I've tested on SeaMonkey 2.20 on Linux, and in Chrome 28.0.1500.95 on Linux. It happens while logged in, and while logged out. And I've never set any "furigana preferences". So I don't think it's a problem on my end.
Any idea what happened to furigana support?
空気{くうき}を読{よ}む, it should look like空気を読む, but with the textくうきandよabove it. Another example is in the title of this question, where the charactersしshould appear above the characters written死.しょandあるshould appear above背負and歩. And in this question and its answer, in the second quote in this answer, in this comment, ...getSettingis being called likegetSetting[...]rather thangetSetting(...). If you replace the square brackets with round brackets, it fixes the problem. (I didn't know you could do that at all, but you learn something new every day!)
