After changing the published date, some strings do not get translated

This bug is for localized version only.

When you change the published date from post edit panel (e.g. /post.php?action=edit&post=1), post status value and "published on" label become English.

Correct translation show up again if you set the date back to when the post was originally saved.

These strings are translated in script-loader.php, lines 275 - 297 and 304 - 320.

They are translated when the page is loaded, but not after post date is changed.

Here's the screencast to replicate the issue (watch around 0:17)

Perhaps check the .po file. The strings for "Save draft" and "Publish on" are translated in script-loader.php and are inserted with js on change.

Both exist in .po file.

They are translated fine as long as you don't update the post date.
(For example when you first load an already-published post's edit page, "Publish on" show up in Japanese)

In order to replicate, please try throwing the .po file in /wp-content/languages/ and modify wp-config.php to
add:

define ('WPLANG', 'ja');

(This is also true in WordPress.com. I've tried it by changing interface language to Portugese - same result)

Think this was fixed some time ago.
