Diagram editor toolbar not working on demo editors

[ysmartin]

Expected

The demo editors available at https://structurizr.com/dsl and https://structurizr.com/json are supposed to show a diagram editing toolbar as explained here https://docs.structurizr.com/ui/diagrams/editor . Indeed, that was the case until a few weeks ago.

Actual

Upon entering the page, the toolbar loads and is briefly shown (see first screenshot below). But, when the diagram is loaded and rendered, the toolbar disappears and becomes inaccessible (see second screenshot).

Steps to reproduce

Browse to https://structurizr.com/dsl or https://structurizr.com/json

Version/build information

N/A (online website).

Severity

Major

Priority

Low (I have no budget and there's no rush, please fix this for free)

More information

I'm using Microsoft Edge 136 on Windows 11 Version 23H2. However, the error is reproduced in other environments (it was another colleague who first mentioned me the issue, using Chrome, Firefox, and Opera).

The toolbar will disappear if automatic layout is enabled, so this looks to be working as expected.
