How to show a diagram from draw.io in an expandable section?

Question

I have created a diagram in draw.io which is visible on a wiki page in Confluence.

However, when I create an expandable section (via macro UI Expand) and drag the diagram into this section, it is no longer visible - only a thin horizontal line is visible. The same effect occurs if I create a new diagram within the section.

The diagrams are all visible when the page is in edit mote, but as soon as I click save it is "replaced" with a horizontal line.

Am I using the wrong macro?

How do I solve the task of showing a diagram in an expandable section on a wiki page?

Thanks a lot! I jumped to conclusion thinking that macro was for text only.

Hi @Carola ,

I tested with the regular Expand-Macro. With that macro, everything seems fine.
