}

What did you do?

Play live video, scrub backwards, click a button that calls go to live. Our player has a live function, and the shaka's UI seems to do the same. (instead of calling goToLive, it goes to seekRange end which is the same (presentation_time.js at around line 40)

What did you expect to happen?
The video would go to the end of the available streaming content.

What actually happened?

The video advanced around 5-10 seconds, it didn't appear to be a consistent interval.

This video shows the bug with the setting turned on, then I turn it off, reload the page and show that it works with it off

Are you planning to send a PR to fix it?
No

@joeyparrish can you review it? (It can be reproduced with Shaka Player History by seeking to the past and then to the present with the UI) Thanks!
