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) 

Start by running the supplied R reproduction with df_all.txt and compare the individual ggplot frames with the ggplotly(g) animation. Investigate the ggplotly animation conversion and consider the issue resolved when both polygons in the first frame and both red bars in the second frame are rendered.
