Can not copy image from Preview Image and Save Image nodes in new Nodes 2.0

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

When Nodes 2.0 is disabled, in the context menu which is accessed by right click you can copy the image that is shown in Save Image and Preview Image nodes.

### Actual Behavior

When Nodes 2.0 is enabled, that copy image option does not exist. You can copy only the node itself within the ComfyUI.

### Steps to Reproduce

Enabled Nodes 2.0
Generate an image.
Right Click on the Preview Image or Save Image.
No Copy Image option presented.

I know that you can download image and then use it, but it's more steps to get to the same result.
