    ********Problem Information********
    ISSUE AREA: Audio / Video

REGRESSION: <Untriaged>

DESCRIPTION:
I’ve set-up a small webpage that reproduces the issue:
http://melatonin64.github.io/gapless-mse-audio/

This webpage uses MSE to append several audio files into a continuous audio stream.
The stream should be gapless as we use SourceBuffer’s timestampOffset, appendWindowStart and appendWindowEnd to discard of padding.

In Edge/IE however, the audio does not play gaplessly.
