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.

Ejecuta el ejemplo reproducible de R usando group_by(id, group), color = ~group y error_y = ~list(array=ci, type = 'data'). Rastrea cómo se procesan los datos agrupados y las barras de error, y verifica después que las barras de error aparezcan en los 8 puntos, no solo en 6.
