Missing polygons in animation

Missing polygons in animation.

The two plant shoots (light green and grey) are expected to reside in one frame, and the two red bars in another frame, but in the animation returned by ggplotly, the light green shoot is missing. How to resolve this issue? Thanks in advance!

# Import the data frame.
[df_all.txt](https://github.com/ropensci/plotly/files/4855628/df_all.txt)

df.all <- read.table('df_all.txt', header=T, row.names=1, sep='\t')
# All frames.
df.all$frame <- as.factor(df.all$frame)
unique(df.all$frame)
# Frame 1.
df1 <- subset(df.all, frame=='HRE2_hypoxia_1')
ggplot(df1, aes(x=x, y=y, frame=frame, group=tissue,value=value))+geom_polygon(fill=df1$color, size=0.2,color='grey70')
# Frame 2.
df2 <- subset(df.all, frame=='HRE2_control_2') 
ggplot(df2, aes(x=x, y=y, frame=frame, group=tissue,value=value))+geom_polygon(fill=df2$color, size=0.2,color='grey70')
# Animation where the light green plant shoot is missing.
g <- ggplot(df.all, aes(x=x, y=y, frame=frame, group=tissue,value=value))+geom_polygon(fill=df.all$color, size=0.2,color='grey70')
ggplotly(g) 

首先使用 df_all.txt 运行提供的 R 复现，并将各个 ggplot 帧与 ggplotly(g) 动画进行比较。调查 ggplotly 动画转换过程，并在第一帧中的两个多边形和第二帧中的两条红色条形都被渲染时，认为该问题已解决。
