sliderTextInput - character choices are being converted to numeric in JS

[tanho63]

The goal here is to update one sliderTextInput with values from another (in-real-app it's to keep one slider in sync with another),
and the values are numeric-like (i.e. character strings that look like numerics).

Reprex

library(shiny)
library(shinyWidgets)
choices <- format((1:50)/10,nsmall = 1)
# choices <- format((1:50)/10,nsmall = 1) |> paste0("M")
sel <- range(choices)
ui <- fluidPage(
  sliderTextInput('s1', label = "Slider", choices = choices, selected = sel),
  br(),
  sliderTextInput('s2', label = "Slider2", choices = choices, selected = sel),
  br(),
  actionButton("set", "set")
)

server <- function(input, output, session) {
  observeEvent(input$set,{
    updateSliderTextInput(session, inputId = "s2", selected = input$s1)
  })
}

shinyApp(ui, server)

If you press the button, the values from slider 1 do not properly get populated to slider 2. It seems like this is silently being converted to numeric in the backend - you can tell because it lost the decimal place on 5.0 and (I think) because this data-type="double" param on the input.

I've managed to work around this by pasting "M" to the end of the choices (i.e. uncomment other choices) and then remove the "M" server-side, but I imagine that this is an unintended bug.
