Should we also include text_input_state.h in this file, even though we don't
access any of the fields?

Per our offline discussion, the forward declaration in the header file should
suffice.

   if (!guest_)
     return;
 
   RenderWidgetHostViewBase* rwhv = GetOwnerRenderWidgetHostView();
   if (!rwhv)
     return;
   // Forward the information to embedding RWHV.
   rwhv->TextInputStateChanged(params);
 }
