Nice, code changes look good to me and huge thank you for providing an example in addition to a test! 💯

One minor nitpick, but otherwise this looks good to me.

It would be nice if the sample showed a playing video, but ultimately the change does seem to work. That error is not reported.

@misteroneill yes, being lazy we set autoplay but that's not having effect. We're just now adding a click listener to play/pause.

[BrainCrumbz]

@misteroneill just to mention that we've made it so that sandbox example can actually play

Hi all. Just wondering if there is any update on this, or something more is needed.
Thank you!

Good news!
No worries, we were just afraid it could remain lost somehow.
