On Nodes 2 submenus ignore the return value of true to keep open

### Prerequisites

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

### What happened?

In Nodes 1, if a submenu callback returned true, the menu remained open.

This does not seem to be the case in Nodes 2.0

### Steps to Reproduce

1. Create a menu item with has_submenu : true
2. Let the callback for that submenu return a value of true
3. Select an entry in the submenu.
The whole menu closes.
