vjs-user-active or vjs-user-inactive aren't added by default

Only until the first triggered event happens does one of these get added.
vjs-user-active should probably be added by default on first play since at that time the user is definitely active.

What's the result of not having it? Could we just add it on init?

[gkatsev]

Yep, basically, things that depend on those don't work quite right immediately after pressing play.
Not certain whether just adding user active on init is a good idea but a lot of css selectors also check for vjs-has-started, so, maybe not a huge issue in that respect.

Yeah, I feel like we can consider the user active when the player is initialized. It at least seems better to have a default state from init instead of waiting until some point later. We could start there and see if it does what we need.

Looks like we already try doing something like this: https://github.com/videojs/video.js/blob/master/src/js/player.js#L202
Looking into switching it out with this.userActive(true) instead.
