Describe the bug The ELK integration in draw.io appears to not function properly. When trying to use ELK for layouts, no layout is applied, and the diagrams do not adjust as expected.

To Reproduce Steps to reproduce the behavior:

1. Open draw.io.
2. Attempt to use the ELK layout engine for diagram organization.
3. No layout is applied, and no error message is shown.
4. The diagram remains in its original state without adjustment.

Expected behavior The diagrams should automatically adjust their layout according to the ELK engine when selected. This was functioning previously but now appears broken.

It's broken at the moment. Mermaid isn't a core part of draw.io, it's support very much "as-is".
