What steps will reproduce the problem?
When playing a segmented audio file using the Media Source Extension sometimes the ended event is never triggered by the audio element.
One example we have is a track duration of 258.4 seconds where the last timeupdate event is reporting the current time to 258.399999 and the end buffer range is also 258.399999.


What is the expected result?
The expected result is for the audio element to trigger an ended event. 


What happens instead?
The music stops by the ended event is never triggered.
