String (Multiline) node inconsistencies, especially when used in subgraphs

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

### What happened?

* Right-clicking on the text input area brings up the web browser menu, not the ComfyUI menu.
* AFAICT the only way to promote the value (text box) widget from inside a subgraph is to create a noodle link input.
* When the node is minimized inside a subgraph, the promoted value (text box) on the face of the subgraph disappears.

### Steps to Reproduce

1. Create a new workflow.
2. Add a String (Multiline) node.
3. Right-click the value (text box) area.
4. **Notice the web browser menu shows up, not the ComfyUI menu.**
5. Right-click somewhere else on the node and convert to a subgraph.
6. Enter the subgraph.
7. Link the value (text box) area as a subgraph input to promote the widget.
8. **Notice this seems to be the only way to promote the widget. **
9. Exit the subgraph.
10. Make note that the value (text box) appears.
11. Enter the subgraph.
12. Minimize the String (Multiline) node.
13. Exit the subgraph.
14. **Notice the value (text box) area has disappeared.**
