Worth noting our use of InternalsVisibleTo are using or being used by same set of components that keep appearing in these issues-- Behaviors, Animations, Media and Extensions.

If our use of InternalsVisibleTo is indeed related to our AoT issues on Wasdk as well as what we've seen here regarding transient dependencies, it might be highlighting a deeper issue with how we've set up these libraries.

We might want to go through and see if we can remove the need for these InternalsVisibleTo, it looks like at least a few are just to avoid helper duplication. If it fixes any of the issues we've listed throughout this ticket, we've narrowed the scope of our search down considerably.
