If we're actually worried about the semantics we could also just add a ``clip_bounds`` option (or similar) rather than providing full control over the render levels. I do think we...

Thanks for the detailed list, this will be helpful. The Plotly backend was always more of a prototype and used to have a big disclaimer saying as much. We probably...
