Describe the bug It's not possible to collapse or expand containers anymore, existing (created in files when they did work) or newly created ones (by grouping the shape). The "-"-sign at the top-left of the shape is visible (so the Extras / Collapse/Expand option is activated) but when clicked, the shape is selected for a brief moment, and then de-selected again (indicated by the edit points of the shape. The Arrange / Group option is greyed out and the Arrange / Ungroup option is selectable.

Containers do work in the online version, both existing ones that were created in files when they did work, and newly created ones by grouping shapes.

To Reproduce Steps to reproduce the behavior:

1. With the mouse, click on the "-" in the top-left corner of the shape Nothing happens. or
2. Create a new shape on the canvas
3. Goto Arrange / Group.
4. With the mouse, click on the "-" in the top-left corner of the shape. Nothing happens.

Expected behavior When a shape is a container, it should behave as one.

Seeing this being important, might I suggest adding this to the New issue template?

I'm not sure if I'm understanding your question "what draw.io binary are you running?" as I've provided the screenshot with the CPU architecture, OS and OS version and the app version I provided earlier.

macOS 14.5, Intel, draw.io app version 24.6.4

Is this sufficient information?
