`ggplotly()` function does not respect line width and does not show legend lines of `geom_linearange()`

Trying to apply ggplotly() to the following ggplot + geom_linerange() resulted in a faulted graph: the line width is not respected (or considered) and the legend does not show the lines for each key (what line of what color corresponds to each entry?)

``` r
library(tidyverse)
library(plotly)

df = tibble(
  task = c("Job A", "Job B", "Job C", "Job A"),
  start = c(0, 5, 10, 6),
  end = c(4, 9, 15, 7), 
  resource=c ('Alex', 'Max', 'Max', 'Alex')
)

p <- ggplot(data = df, 
            aes(x = start, 
                y = task
            )
) +
  geom_linerange(aes(xmin = start, 
                     xmax = end, 
                     color = resource
  ),
  size = 5.5,
  alpha = 0.76
  ) +
  labs(x = "Time (s)",
       y = "Tasks",
       color = "",
       title = "Gantt plot (ggplot)")

print(p)

ggplot output:

but ggplotly:

ply <- ggplotly(p)
print(ply)

output:

Inizia eseguendo l’esempio R riproducibile dell’issue con ggplotly() e confrontalo con l’output di ggplot. Traccia come viene convertito geom_linerange() e come il suo size e il mapping del colore di resource arrivano al grafico interattivo. Il lavoro è completato quando il grafico convertito rispetta la larghezza della linea richiesta e la legenda mostra linee rappresentative per ogni risorsa.
