Comment (by derrod):

 The file was created by an external source and indeed appears to be
 missing the "STYLE" keyword of the style block
 (https://www.w3.org/TR/webvtt1/#webvtt-style-block). However, even if the
 STYLE keyword is added the file is not parsed correctly and the output
 remains empty.

 At least Chrome still appears to render the output correctly however
