Javascript alert message not close

In version 6.2.8, when an alert appeared, it waited a few seconds and closed the message.

In version 8.2.7 the alert appears but never closes. The macro waits until you manually close the alert

Hi, do you have a test case for us? It works ok in my test:

{
  "Name": "JS1",
  "CreationDate": "2023-3-9",
  "Commands": [
    {
      "Command": "open",
      "Target": "https://www.w3schools.com/js/tryit.asp?filename=tryjs_alert",
      "Value": "",
      "Description": ""
    },
    {
      "Command": "selectFrame",
      "Target": "id=iframeResult",
      "Value": "",
      "Description": ""
    },
    {
      "Command": "click",
      "Target": "xpath=/html/body/button",
      "Value": "",
      "Description": ""
    }
  ]
}

I don’t see the alert window, in my case the alert window is shown
