Used CC file with long name: hereisareallylongfilenameforthisclosedcaptionfilesowecantestlongfilenames.vtt

RESULT: The really long file name seems fine - CC file still works properly.

CC file with a bunch of spec char in body

CC file with header but otherwise blank body.

CC with 2 periods in file name (2_periods..vtt)

CC filename with spec char (@.vtt)

CC file name with spec char ($.vtt)

A video created by the class about weather.

No WEBVTT header at top of file.

RESULT: Captions still appear on the screen, but instead of clearing away in order to show the newest line, they just stack up so the screen becomes crowded with the lines (https://www.screencast.com/t/NKOtY8mGZ7a6).
