Subgraph Functionalities broken (and more)

### 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

To work as expected

### Actual Behavior

At least since last Update broken is:

* Copying and Pasting images from one LoadImage to another in Subgraph does not work any more
* List entries from Power Lora Loader (rgthree) not showing up any more in closed Subgraph, but the empty space fro the is reserved, which means empty space for exactly so many items that should have been shown
* In Subgraph shown text fields stay as "ghost" textfields on workspace when subgraph is minified

Tried with completely deleted Browser-data and different Browsers (Chrome and Firefox) on two different OS.
No error messages are shown.

OMG:

After switching to Nodes 2.0:
* List entries from Power Lora Loader (rgthree) show up again on Subgraphs, but are not interactive (can't turn them on or off or change Strength Value)
* List entries from Power Lora Loader (rgthree) DO NOT show any more in the Power Lora Loader (rgthree) in a open Subgraph
* Layout order of Subgraph elements in closed Subgraph not respected any more after a change in "Shown on node" Configuration tab on the right
* Node Properties gone? Where do I get a nodes Properties from now? - When I click on "Node Info" the sidebar Node Tab opens just with the search and the list of all nodes. So how do I get the Info about the Node if I don't know it's name?
* For example: Reroute (rgthree) does not show it's title any more, just a "frontend_only" Label. - How should that work if you don't know by Title where the Reroute is connected to, what it's for?
* Fast Groups Bypasser not working any more although display seems correct

After switching back from Nodes 2.0:
* Suddenly random in a Subgraph contained text boxes showed up in the folded, but not minimized Subgraph that were not configured to show up
