WebVTT cues that begin at 0 do not display
I found this while trying to complete a WebVTT implementation report. The Web Platform Tests mostly use vtt files with cues that begin at 0. Something like
WEBVTT
00:00::00:000 --> 00:00:10:000
This is a test cue
Adjusting the start time to be even 1 ms, caused the cue to display
WEBVTT
00:00::00:000 --> 00:00:10:000
This is a test cue
The WebVTT examples are also attached.
This was tested on VLC 3.0.6 on macOS 10.14.2.
