ggplotly ignores aesthetics other than colour for geom_density

[humburg]

When aesthetics other than colour are used to distinguish groups these are ignored by ggplotly. This is particularly problematic in cases where there is more than one grouping variable.

A simple example:

library(plotly)
data(iris)

p <- ggplot(iris, aes(linetype=Species)) + geom_density(aes(x=Petal.Length))
p # works as expected
ggplotly(p) # shows only solid black lines
