RenderUI issue with material_slider

The material_slider tooltip doesn't appear while using renderUI

[jameswcraig]

Hi @ericrayanderson I'm also attempting to use material_slider with renderUI and can confirm that it is indeed not working. Tooltip does not appear and slider input values are NULL.

See reprex below:

ui <- material_page(
  uiOutput("sliders")
  
)

server <- function(input, output, session){
  
  output$sliders <- renderUI({
    render_material_from_server(
      tagList(
        material_slider(input_id = paste0("slider", 1), label =  paste0("slider", 1), min_value = 0, max_value = 20, step_size = 1, initial_value = 1),
        material_slider(input_id = paste0("slider", 2), label = paste0("slider", 2), min_value = 0, max_value = 20, step_size = 1, initial_value = 1),
      )
    )
  })
  
  observe({
    print(input$slider1)
    print(input$slider2)
  })
}

shinyApp(ui, server)

As always, thanks again for your work on this package and looking into this issue further.

Related to #114 - I've also had a go and can't get this working, same sort of issue for material_radio_button()
