fix: prevent invalid media processing

[juliecheng]

👋 hello! i'm seeing h.pause is not a function errors/warnings during playback and after looking into the issue some more, it looks like during playback we can end up adding non-media elements to the mediaMap via mediaMutation, which is what's causing some errors during playback.

to summarize the changes in this pr:

1. protect against MediaInteraction events (mutations) being applied to non-media elements otherwise we'll see errors during playback
2. exit early out of addMediaElements if a media element is blocked since it won't have any media attributes anyway

@eoghanmurray hi eoghan! just a heads up that my pr looks like it might be trying to resolve the same (or at least similar) issue as your pr here #1673 if my changes here look good i'm happy to close this one out and merge the changes into your pr instead if that's preferred (or vice versa). thanks!
