BPMN Editor: Properties Panel Not Loading for Selected Nodes

[grousse]

In our React app, we're using the BPMN standalone editor and encountered an issue where the properties panel fails to load for some tasks.

Versions:

react: 18.3.1
node: >=22.9.0
@kie-tools/kie-editors-standalone: 10.0.0

We load a BPMN template during editor open that contains four nodes in the following order: Start, Script, User Task, End.

When clicking on the Script task, the properties panel does not load. Clicking on the Start, User Task, and End nodes works as expected.

Steps to Reproduce:
Open the editor with a BPMN file containing:

Start -> Script -> User Task -> End

Click on the Script node.

Actual Behavior:
The properties panel does not display any content for the Script node.

Expected Behavior:
The properties panel should display the Script task's properties when selected.

Workaround:
If the Script node is temporarily changed to a User Task, and then changed back to a Script, the properties panel begins working correctly.

Additional Notes:
The issue appears to affect Script nodes during the initial load but also, rarely, other nodes while working in the editor.

Creating new Script task manually works fine.

Comparing the BPMN XML between working and non-working cases shows no differences, indicating the issue likely lies in the BPMN editor UI, not in the XML itself.
