GraphElement resize flag works without manual implementation (documentation claims otherwise)

**Your Godot version:4.4.1 stable**

**Issue description:
"Note: Dragging the handle will only emit the [resize_request](https://docs.godotengine.org/en/4.4/classes/class_graphelement.html#class-graphelement-signal-resize-request) and [resize_end](https://docs.godotengine.org/en/4.4/classes/class_graphelement.html#class-graphelement-signal-resize-end) signals, the GraphElement needs to be resized manually."
This is not true. The resizing is handled automatically somewhere and I have no idea how resizing should be modified.
