/**
* This should be the base class of any actor class registered via
* ActorManagerParent and implemented in the child process. It currently takes
* care of setting the `mm`, `content`, and `docShell` properties based on the
* message manager it's bound to, but may do more in the future.
*
* If Fission is being simulated, and the actor is registered as "allFrames",
* the `content` property of this class will be bound to a specific subframe.
* Otherwise, the `content` is always the top-level content tied to the `mm`.
