Unused aesthetic in scale_*_manual causes ggplotly conversion to fail #2466
Description
If you create a manual colour scale mapping for an aesthetic that isn't used {ggplot2} doesn't care, but {plotly} cannot successfully convert the plot.
This might show up if you try to create an organisational colour scale theme you want the user to use as a one liner, without care for the underlying aesthetics in play (works well with native ggplot2).
