Document or provide guidance on expanding/theming cell for a larger height

Within a Notebook in AML it doesn't appear possible to customize the height of the rendered Cell, at least within the context of rendering html, but likely in general. If I render html, the css that controls the max-height is above the rendered cell dom, making it impossible to override with css.

The notebook theme is:

```
.nteract-cell-outputs:not(.expanded) {
max-height: var(--theme-layout-output-max-height);
}
```
I know this is the correct place to alter since altering it manually in the DOM increases the cell size to anything I want, but it's not possible to override this in the dom since the rendered cell is a child.

- Can I override this by providing a custom theme?
- The selector would indicate that there is the ability to expand the cell, but I see no such option in the UI.

Below is a screenshot of the rendered cell where you can see the image is cut off, I want to show probably least 1000px or 90% of the vh.


Empieza reproduciendo la celda HTML renderizada en un AML Notebook e inspecciona la regla `.nteract-cell-outputs:not(.expanded)` y `--theme-layout-output-max-height`. Determina si un tema personalizado puede anular la altura y si existe un control de expansión en la UI. Se considera completado cuando se documente la forma compatible de mostrar una salida más alta, o se indique claramente la limitación y la solución alternativa disponible.
