vtt.js: Safari 10.1 throws Error: The provided value is non-finite

When using vtt.js in Safari it throws Error: The provided value is non-finite on this part cue.line = settings.get("line", "auto");.

I think this is an issue in the Safari VTTCue implementation, but I hope to find a workaround in this polyfill.

Below the stacktrace:

macOS Sierra 10.12.4
Safari Version 10.1 (12603.1.30.0.34)

Here’s what we do in jwplayer:

var line = settings.get('line', 'auto');
if (line === 'auto' && defaults.line === -1) {
    // set numeric line number for Safari
    line = -1;
}
cue.line = line;
