Update Button badly mixes legenditems of plot (`updatemenus`)

Hi, I´ve come across a weird thing:

I tried the plotly "Update Button" on a plot with a legend. At first everything seems as expected. But as soon as you toggle the plot with help of the update button, the legend is mixed in odd ways. Sometimes the legend even does not correspond to the data at all (e.g. change sensors to 4 in reprex).

Heres an example to play around

library(plotly)

df <- data.frame(
  car =    c(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2), # two cars
  sensor = c(1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5), # with 5 sensors
  x =      c(1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2), # sensor data
  y =      c(2, 1, 3, 5, 6, 5, 3, 2, 1, 6, 7, 3, 8, 1, 5, 9, 2, 2, 5, 5)
)

updatemenus <- list(
  list(
    type = "buttons",
    buttons = list(
      list(
        label = "Car 1",
        method = "update",
        args = list(list(visible = list(T, F)))),
      list(
        label = "Car 2",
        method = "update",
        args = list(list(visible = list(F, T))))
    )
  )
)

fig <- plot_ly(type = 'scatter', mode = "lines")
fig <- fig |> add_lines(~x, ~y, data = df[df$car == 1,], name = ~sensor)
fig <- fig |> add_lines(~x, ~y, data = df[df$car == 2,], name = ~sensor, visible = FALSE)
fig <- fig |> layout(
  updatemenus = updatemenus,
  legend = list(title = list(text = "<b> Sensor </b>"))
  )

fig

Commencez par exécuter le reprex R fourni avec les boutons de mise à jour de plotly en faisant varier le nombre de capteurs. Suivez l’effet des mises à jour de visibilité de updatemenus sur la légende, puis vérifiez que chaque bouton laisse des éléments de légende correspondant aux données actuellement visibles et que l’exemple existant n’affiche plus d’entrées mélangées.
