"select taxonomy by language" does not work in admin when admin language is different than node language

The "select taxonomy terms by language" provided by the Multilingual Select submodule seems to use the page language, not the node language, for filtering taxonomy.

That works great in most cases, when the language of the page matches the language of the node. That's the case you are in when you use the "translate" tabs for editing nodes.

However, if you go to /en/admin/content , and click "modify" on a german node, the taxonomy field ( I am talking "translate" type of taxonomy, not "localized" type. see http://drupal.org/node/1114016 ) picks up the english (page language) taxonomy terms, not the german (node language) ones.

Wouldn't it better to use the node language, not the page language, in "select taxonomy terms by language" ?
