event_data("plotly_selected") is not working with type="scatter" and mode="lines"

In my shiny app, I am trying to see a list of data points on a line plot after the selecting a specific region on the chart but getting the list() output. I used event_data("plotly_selected", source = "A") to get the selected field data.

Below is my plotly code:

nms = row.names(mtcars)

plot_ly(mtcars, source = "A") %>%
add_trace(x = ~mpg, y = ~wt, key = nms, type="scatter", mode = "lines")

The plotly_selected event won't fire when mode="lines", but you could use this 'trick':

plot_ly(mtcars, source = "A") %>%
add_trace(x = ~mpg, y = ~wt, key = nms, type="scatter", mode = "lines+markers", marker = list(size = 0.1))
