Code changes generally look good to me.

Could you sync up with me offline with an example video that you used to test this? I'm curious about the "Play" button state, but I suspect there's no issue.

[mportiz08]

I realized what I was confused about since the "Play" state is only something that can be seen with the other PR for introducing the new Video support within content blocks, although it's not technically a dependency here.
