"Auto (Recommended)" is supposed to show a caption track only when 1) the language of the file's primary audio track doesn't match the user's preferred language, 2) a track in the user's preferred language is available, and 3) no other track is enabled.

The current behavior is a bug, the captions in this file should not show automatically when "automatic" caption mode is enabled.
