### Godot version

4.1

### System information

Fedora, RX 590

### Issue description

Between 4.0.2 release and 4.0.3 RC1 the hotzone of the visual shader nodes have shrunk on the side that overlaps the node itself.

### Steps to reproduce

Download 4.0.2 release and 4.0.3-rc1. 

Open MRP, navigate to hotzone.tres shader.

Zoom out to this level of zoom:

Try to extract a pin from ColorOp node.

In 4.0.3 you can observe how if you're not very precise you will drag the node around.
