That is the expected bahaviour and currently our best option to hint compatibility bounds of optional dependencies to the user.

If you don't need to save your plot to file you are free to ignore that warning otherwise it would be good to either add a compat bound for PlotlyBase to your environment or pin PlotlyBase to the latest 0.7 version.
