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

まず、提供された R reprex を plotly の更新ボタンとともに実行し、センサー数を変化させます。updatemenus の可視性更新が凡例にどのような影響を与えるかを追跡し、各ボタンによって現在表示されているデータに一致する凡例項目だけが残ること、また既存の例で混在した項目が表示されなくなっていることを確認します。
