Some error bars are missing when using multi-variable grouping

When using group_by and color, some of the error bars seem to disappear.

data <- data.frame(group = rep(c('A','B'), each = 4), id = rep(c(1:4), each = 2), x = runif(8), y = runif(8), ci = runif(8)/4)

data %>% 
  group_by(id, group) %>% 
  arrange(x, .by_group = T) %>%
  plot_ly( x = ~x, y = ~y, 
           color = ~group, 
           type ='scatter',
           mode='lines+markers',
           error_y = ~list(array=ci, type = 'data')
          ) 

Result: error bars are present on 6 out of 8 points.

使用 group_by(id, group)、color = ~group 和 error_y = ~list(array=ci, type = 'data') 執行可重現的 R 範例。追蹤群組資料和誤差線的處理方式，然後確認誤差線是否出現在全部 8 個點上，而不只是 6 個點上。
