Boxplot outliers are shown in black using ggplotly

If I create a boxplot in ggplot2 and convert it using ggplotly command, the outliers are outlined in black.
Here is a simple example:

library(ggplot2)
library(plotly)

p <- ggplot(mpg, aes(class, hwy))
g <- p + geom_boxplot(aes(colour = "red"))
ggplotly(g)

ggplot would show this chart:

whereas plotly would show this chart:

Is this something that can be fixed?

使用 ggplot2、geom_boxplot 和 ggplotly 重现所提供的 R 示例，然后检查 ggplotly 如何处理 boxplot 的颜色 aesthetic 和离群值样式。当 boxplot 颜色设置为红色时，转换后的图不再为离群值添加黑色轮廓，同时保留示例中报告的行为，即表示完成。
