geom_ribbon_interactive hover not selecting both ymin and ymax

[glaroc]

When adding hover interactivity to a geom_ribbon_interactive, it does not apply the same interaction to the lower and upper envelope.

For example, with this:

library(ggiraph)
tt <- data.frame(y=sort(rnorm(100)),z=rep(c(1,2),50))
tt[tt$z==2,'y']<-tt[tt$z==2,'y']*2
gg<-ggplot(data=tt,aes(x=1:100,y=y,group=z,color=z,data_id=z))+
  geom_line_interactive()+
  geom_ribbon_interactive(aes(ymin=y-0.4,ymax=y+0.4), alpha = 0.2)

g<-girafe(ggobj = gg,  width_svg = 9,  height_svg = 5, options = list(
  opts_hover_inv(css = "opacity:0.1;"),
  opts_hover(css = "stroke-width:2;")
))
g

when hovering over one of center line or the upper lines, the associated bottom line is not selected.
