geom_smooth does not show up when text option is added to aes

Hi everybody,

I want to plot the data and added a smooth curve (LS line for example) but the smooth curve does not show up when the text option is added to aes() (Eventually I want to use ggplotly and need to add additional information to the tooltip, hence the text option). Could somebody help me sort out the problem? I am using Windows 10, R 4.0, R-Studio 1.3.957, ggplot2 3.3.0. Thanks.

It seems to work if you include the aes(text = ...) just in geom_point() and not for all the geoms.

library(tidyverse)

df = tibble(Sample = letters[1:5], GMT=c(8,14,18,21,22), RSD=c(47,6,29,36,30))

p <- ggplot(df, aes(x=GMT, y=RSD)) +
  geom_smooth(method='lm') +
  geom_point(aes(text=paste('Sample:', Sample)))
#> Warning: Ignoring unknown aesthetics: text

p
#> `geom_smooth()` using formula 'y ~ x'

plotly::ggplotly(p)
