Description
Hi,
The following is affecting my ability to use ggplotly:
When color = Species and group = 1, all dots should be connected, irrespective of species, but ggplotly does not respect the group variable and it is as if I only wrote color = Species.
Thanks for your work on this great library! If there is a workaround please let me know.
With ggplotly:

only ggplot:

ggplotly(ggplot(data = iris) +
geom_line(mapping = aes(Sepal.Length, Sepal.Width, color = Species, group = 1)) +
geom_point(mapping = aes(Sepal.Length, Sepal.Width, color = Species, group = 1)))

Research direction
Start with the provided ggplotly call using iris, geom_line, geom_point, color = Species, and group = 1, then compare its output with the plain ggplot result. Trace how ggplotly handles the group variable when a color variable is also mapped; done means dots are connected across species as in the ggplot output.
