ggvis Cannot add layer_smooths() when x or y is interactively selected

Cannot add layer_smooths() when x or y is interactively selected

I looked at vignettes but I did not find a way to make this works. I can use shiny in this case, but it would be great if this can be done with ggvis alone.

library(ggvis)
library(dplyr)

# works
mtcars %>% 
    ggvis(~mpg, ~wt) %>% 
    layer_smooths()

# does not work
mtcars %>% 
    ggvis(~mpg, input_select(names(mtcars), map = as.name)) %>% 
    layer_smooths()
# Error: Visual property y.update is not a variable

# works
mtcars %>% 
    ggvis(~mpg, input_select(names(mtcars), map = as.name)) %>% 
    layer_points()

# does not work
mtcars %>% 
    ggvis(~mpg, input_select(names(mtcars), map = as.name)) %>% 
    layer_points() %>%
    layer_smooths()
# Error: Visual property y.update is not a variable
