See my earlier comment.

Acknowledged.

There are 4 IPCs. I think having it temporarily like this might be better. What
will happen here soon is that I will return
text_input_client_observer_->OnMessageReceived() in this block (after ownership
is brought to RenderWidget).

I also need to return after the observer call.
