The way I see it, the browser is working like a video player.  Modern
video players allow users to configure if they would like to see the
first subtitles track by default or not.  And if the user wishes to
turn subtitles on, off, or switch to another subtitles track (e.g.
another language) s/he right clicks the video screen and modifies the
subtitles options.  Not elegant, but it works.
