IE only: Also, Ended doesn't seem to fire? Play button does not re-appear at the end of playback.

Also notice this for Muliperiod content at end of period in all browsers except chrome. May not be related but wanted to add note. Also noted in MP issue #1033

Seems to just be issue with UI controlbar.js Not listening to right event apparently for Ie will solve. But in IE console I see all the right logs

[87781] Getting the next request at index: 15
[87781] Signal complete.
[87781] Schedule controller stopping for video
[87782] Stream is complete
[117499] Native video element event: ended

[Only with IE] the pause state not set at end of stream. So I manually do this to ensure event. Seems like right behavior beyond the contrib control bar needs isPaused true when toggling the icon as well as needs either ended or paused event.

It works well and solves the issue while maintaining other browser's event order at end of stream. In fact this levels the playing field so all browsers now see pause event followed by ended event.
