fix: Send wireframe children for updated wireframes - mutation

[marandaneto]

💡 Motivation and Context

When there are keyboard events (open/close), the view is redrawn and the wireframe has a new height due to making space for the keyboard hence the wireframe observed a mutation.
The mutation sends just the wireframe but not its children leading to all children being lost in the FE since its stateless.

💚 How did you test it?
