* 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`.
