Can you implement geom_GeomTextNpc() in plotly ?

[FannyVille]

Hi,
I'm using the package ggpmisc to display on ggplot graphique the R² and equation of regression thanks to ggpmisc::stat_poly_eq().
This is working well when I am plotting the ggplot graphic. But when I want to use the function ggplotly() to display the graphic, the R² and the equation disappear.
I receive this messages :
Warning message: In geom2trace.default(dots[[1L]][[1L]], dots[[2L]][[1L]], dots[[3L]][[1L]]) : geom_GeomTextNpc() has yet to be implemented in plotly. If you'd like to see this geom implemented, Please open an issue with your example code at https://github.com/ropensci/plotly/issues

If you have the time, and the desire to implement geom_GeomTextNpc() in plotly, it could be super nice.

I give you a small code to reproduce the problem

#Data cration

df<-tibble(a=c(2,6,3,4,10),
           b=c(3,6,9,12,15))
df

#relation
myFormula<- y ~ poly(x,2,raw = TRUE)

#ggplot
df_plot<-ggplot(data = df,aes(x = a,y = b))+
  geom_point()+
  geom_smooth(method = lm,
              formula = myFormula)+
  ggtitle("polynomial 2")+
    #from here problem with ggplotly
  ggpmisc::stat_poly_eq(
    aes(label=paste("atop(",stat(rr.label),",",
                    stat(eq.label),")",
                    sep="")),
    formula = myFormula,parse = TRUE)

df_plot

#plotly
ggplotly(df_plot)

The ggplot graphic :

And here the graphic with plotly:

Thank you for creating and implementing plotly 👍
Best,
