Thread:Extension talk:TimedMediaHandler/Subtitles

I installed this extension on my wiki, uploaded an .ogg file and created corresponding TimedText file with subtitles. The media players on the file page in File: namespace and on the subtitles page in TimedText: do display subtitles. However when I embed the player in the main namespace with, no subtitles button appear on the player. Is it how it should be?
