Color group does not appear in the animated plotly

I am trying to plot an animated frame with plotly. The goal is to plot how some units (id) changes in two continuous variables AND one categorical. The problem arises because the third category appears not from the beginning. In the plot, the units with “type3” category do not appear on the plot after 2001 and the ‘type3’ entry does not appear in the legend. The code shows an example of the data structure and problem. The same problem with boxplot - only two categories are present for all frames.

The ideal result is appearing of all 3 groups form the beginning. For scatterplot, points should change the color and for boxplot there should be an empty space from the beginning for the third category or it should appear after reaching the proper year.

df <- data.frame(x = rnorm(50), 
                 y = rnorm(50), 
                 year = c(rep(2000, 10), rep(2001, 10), rep(2002, 10), rep(2003, 10), rep(2004, 10)),
                 id = rep(1:10, 5),
                 model = c(rep('type1', 5), rep('type2', 5), rep('type1', 5) , rep('type2', 5),
                           rep('type1', 3), rep('type2', 2), rep('type3', 5) ,
                           rep('type1', 4), rep('type2', 5), rep('type3', 1) ,
                           rep('type1', 3), rep('type2', 2), rep('type3', 5) ))

cols <- c(
  "type1" = "#bc80bd",
  
  "type2" = "#fdb462", 
  "type3" = "#b3de69"
)



plot_ly(df,  x = ~x, 
        y= ~y, 
        color = ~model,
        text = ~id,
        frame = ~year,
        opacity = .8, 
        marker = list(size = 10),
        colors = cols,
        type = 'scatter')

plot_ly(df, 
        y= ~y, 
        color = ~model,
        frame = ~year,
        opacity = .8, 
        colors = cols,
        type = 'box')

まず、アニメーション付きの散布図と箱ひげ図用に提供されている R の例を実行し、その後、年ごとのフレーム間でカテゴリ凡例とトレースを比較します。type3 が最初から一貫して処理され、散布図で期待される色と凡例の動作、および箱ひげ図で空または後から表示される状態が定義されていれば、issue は解決です。
