If an inner doc is added via BrowserParent::RecvPDocAccessibleConstructor it will call DocAccessibleParent::AddChildDoc which will call DocAccessibleParent::RecvEvent.
Both Recv functions hold a monitor auto lock and we end up hanging.

We rely on Recv events to be called from child processes and not from
other Recv events. If this happens we risk reentry in regards to the
android monitor lock.
