SaveImage Node in SubGraph does not show the image

### Custom Node Testing

- [ ] 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

I tried to create a SubGraph with a few nodes in it of which two nodes ate SaveImage nodes.

I expected the images to show but could not find a way to do that.
What am I doing wrong or is it even not possible that the images are displayed?

Many thanks in advance

### Actual Behavior

Images are not shown/displayed in the folded/compressed SubGraph.

### Steps to Reproduce

Create a Subgraph with a SaveImage node in it.
