Broken custom node initialization for Custom Elevation Profile Sources #65058
Description
What is the bug or the crash?
For instance, plugins that create and register a Custom Profile Source cannot see a corresponding custom node in the Elevation tree view anymore (in the current master, 3.99).
Expected behavior when registering a Custom Profile Source (like SwissLocator plugin does): the custom node at the top.
Steps to reproduce the issue
- Open a new project.
- Register a Custom Profile Source (e.g., by running this code snippet: https://gist.github.com/gacarrillor/4bb82379e4fa30df500c5532be1c9a13, you can verify the Python console, which prints
Trueif the Custom Profile Source was registered). - Open an Elevation Profile widget.
Current result: The custom node is not in the Elevation layer tree.
Expected result with the code snippet provided above:
