Expected Behavior

What did you expect to happen instead?

WebVTT parsing should be the same level or better than Seattle

Boston event gather log for where closed caption is pulled from: https://github.com/CouncilDataProject/boston/runs/6759035563?check_suite_focus=true#step:9:7200

[evamaxfield]

Seems like you should be able to pull that same URL: http://boston.granicus.com//videos/87/captions.vtt

and test out changes locally
