Description
A short example:
library(ggplot2)
p <- ggplot(economics_long, aes(date, value01, colour = variable)) +
geom_line(size = .5) +
guides(colour = guide_legend(override.aes = list(size = 2)))
p
Notice the thicker lines in the legend on the right
However, this new element is ignored in ggplotly:
ggplotly(p)
This becomes even more critical when using a very low level of alpha, and then needing to adjust it for the legend.
Thanks.

Research direction
Start by running the R example with ggplot2 and ggplotly(p), comparing the ggplot2 and interactive legend results. Trace the ggplotly legend conversion entry point and verify that guide_legend's override.aes values, including size and alpha, affect the rendered legend.
