This is confusing when you navigate elsewhere in the graph to paste a node, then when you paste it appears that nothing happens.
Node is pasted at the location of the original node - you will have to go back to drag it to your desired location.

1. Create a new project.
2. Install the Shader Graph package. (Window -> Shader Graph)
3. Create a new graph. (i.e. Assets -> Create -> Shader -> Unlit Graph)
4. Open the new graph in the shader editor.
5. Create a random node. (i.e. Right Click in Shader Editor -> Create Node -> Artistic -> Adjustment -> Channel Mixer)
6. Copy or cut the node. (Right Click Node -> Copy/Cut)
7. Move the mouse to where you'd like to paste the node.
8. Paste the node with the mouse. (Right Click -> Paste)

Expected Outcome: The node is pasted at the location of the mouse.
Actual Outcome: The node is pasted just slightly offset from the original node location.

Reproducible in package version 7.1.6, 1.1.8.
Could not get an earlier package version working without error, assuming not an regression.

Note:
- In VFX graph, while it doesn't quite paste at the location of the mouse, it pastes to the center of the visible screen.
- Tested on Windows.
- GIF attached demonstrating this issue.
