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) 

Inizia eseguendo la riproduzione R fornita con df_all.txt e confronta i singoli frame ggplot con l’animazione ggplotly(g). Analizza la conversione dell’animazione ggplotly e considera il problema risolto quando vengono renderizzati sia entrambi i poligoni nel primo frame sia entrambe le barre rosse nel secondo frame.
