[webvtt] Why TextTrackCue's endTime is Inifnity On s (#513)

valletgood has just created a new issue for https://github.com/w3c/webvtt:

== Why TextTrackCue's endTime is Inifnity On s ==
When playing HLS live content in Safari, the subtitles continue to be displayed and are not disappearing. When checking the activeCues through the Web API textTracks, it was found that some cues have an endTime of Infinity. When playing the same live content in Chrome, the issue does not occur. What is the reason for assigning the value of Infinity to endTime when processing the received startTime and endTime of the subtitles from the server in Safari? The first screenshot shows the data received from the server, and the second screenshot shows the data obtained through the textTracks API. The server continuously sends time data, but Safari is not able to process it properly. What could be the reason for this?
