Example application or steps to reproduce the problem

inputModuleUI <- function(id) {
  numericInput(NS(id, "amount"), "amount", 10, min = 1, step = 1)
}

inputModuleServer <- function(id, data, filter = is.numeric) {
  moduleServer(id, function(input, output, session) {
    reactive(input$amount)
  })
}

testApp <- function() {
  ui <- fluidPage(
    inputModuleUI("mod-1"),
    verbatimTextOutput("myOutput"),
    actionButton("action","refresh")
  )
  
  server <- function(input, output, session) {
    output$myOutput <- renderPrint({
      input$action
      server_output <- inputModuleServer("mod-1")
      server_output()
      })
  }
  shinyApp(ui, server)
} 

Describe the problem in detail

I'm amoduleServer to return the value from a numericInput in the matching UI module. This UI is called by the main ui of the app, and displayed via a verbatimTextOutput.

This works initially but the output can become stuck when adjusting the amount via the arrow tools. I've attached a short video which demonstrates this problem. Notice how when the number 28 is reached the output no longer updates until the refresh button is pressed. This happens again later when I reach the number 25.
