Not a big issue because only tests create 2 ACs now and the tests and AC itself will be removed as soon as I can get past these leaf issues.

Going further back it still doesn't seem to be the case that it was an AC fix.
It was actually due to a security issue with ACC (AccessControlContext).
That fix is now no longer there because we removed SM code a couple of releases ago.
Now we can simplify it even further.

But it still doesn't seem like we need to resurrect using the visible field.

> The only difference between the two is that the old MediaTracker component was created using createComponent, which resets the AppContext, should we drop that AppContext usage there as well?

Yes, I don't know why I didn't do that.
