Language files for TinyMCE dialogs aren't loaded for official TinyMCE plugins (like advlink)
|Reported by:||johnconners||Owned by:||azaozz|
I use a WordPress plugin I've written that adds a few TinyMCE plugins not installed as standard by WP. I noticed that  prevents the strings being loaded for the plugins that have popups. Attached is a screenshot of the advlink popup in action showing the problem.
Unwinding  corrects the problem so I can confirm that's the changeset that introduces the behaviour.
The advlink plugin (along the other TinyMCE plugins that have popup dialogs I've looked at) have in the 'langs' subfolder 'en_dlg.js'. If I rename that file to 'en.js' and reload WP then when I click the link button while editing a post the language strings are loaded properly.
I can see in  that while en.js is searched for, en_dlg.js isn't. Worth noting that some plugins have both en.js and en_dlg.js.
