Images and mermaid diagrams are not zoomed-in on click

[renardeinside]

Now sure if this is considered as a bug or not, but in most documentation systems (e.g. mkdocs-material), embedding images or mermaid diagrams also makes them zoomable on click. Unfortunately seems it's a missing feature in Hextra/Hugo.

I wouldn't consider it a bug, but rather a new feature / enhancement.

Making images or mermaid diagrams zoomable is likely to introduce additional dependency which is less ideal.
Let's see if there's further demand for this feature.
