If I embed a Draw.io graphic on a published confluence page if I mouse over the diagram, a grey header box appears around the diagram with; pencil (edit) + / - magnification and expander icons.
If you arbitrarily click inside the diagram it opens the drawing in its own window which is weird.
I don't see the logic in allowing these icons or opening of the drawing by itself if you click it. I don't want my users to be able to edit the diagram unless you are actually editing the page.
