For questions, (like this one), where multiple posts use tags like #English or #日本語 to provide multiple language versions, if I click on the language toggle (eg "English" to switch to the English version of a post), the actual contents of other multi-language posts disappear entirely. However, the meta-information and language toggle buttons remain on these other posts.

Work-around: clicking one of the language buttons of a "disappeared" post will restore its contents.

More details: For "disappeared" posts, none of the language buttons is underlined, which suggests maybe the problem is that post is being rendered in a "null" language for which there is no data.

There was an issue in the japanese-l-u.js script. The fixed script will be available as soon as build rev 2016.6.28.3711 rolls out.

Detective work

The $.each function returns String objects as this when using it to iterate over an object.

jquery each on object

Furthermore, the above is a result of .bind/.apply/.call operations on a string primitive in JavaScript:

javascript bind to string

And of course, calling the equals operator on two String objects, even though they have the same value, returns false:


The fix was pretty straightforward:
