`guide_legend(reverse = TRUE)` does not reverse legend order

I reversed the legend order with guide_legend(reverse = TRUE), but the legend is unchanged in the plotly plot. The ggplot version is reversed.

library(plotly, warn=FALSE)
#> Loading required package: ggplot2

set.seed(123)

df <- data.frame(x = rnorm(10), y = rnorm(10), group = rep(c("A", "B"), times = 5))

p1 <- ggplot(df, aes(x = x, y = y, color = group)) +
  geom_line() +
  guides(color = guide_legend())
# Legend order default

# Plot with guides
p2 <- ggplot(df, aes(x = x, y = y, color = group)) +
  geom_line() +
  guides(color = guide_legend(reverse = TRUE))
# Legend order reversed

# Convert ggplot with reversed legend order
ggplotly(p2)
# Legend not reversed

まず、提供された R の例を実行し、ggplot の凡例と ggplotly(p2) の結果を比較します。次に、guide_legend(reverse = TRUE) に対する ggplotly の変換経路を追跡し、変換後のプロットで凡例の逆順が維持されていることを確認します。
