[Photoshop UXP] alert and confirm modal functions stopped working after an update

Hello! I want to raise what I think is an issue I found with the Photoshop API.
In a plugin that I'm developing for Photoshop using UXP, I was relying on the alert and confirm functions (which according to the last docs I could find here should be supported) but after a certain update, they are simply not defined.
I'm still trying to track down the exact version where this stops working but having the same piece of code I can see a modal for sure in version 25.3.1:

(title blurred in red just due to sensitive information)

But running the same piece of code in the current last version 25.6 I'm getting the following error:

Sadly I can't share the code I'm running due to license. I'll probably keep tracking down the version where this issue starts happening and will work on isolating the issue in a new sample plugin, just to make sure this bug is not coming from another issue in this project

I've found the info that this is a change that came with "Photoshop Beta 25.5 (February 2024)"

UXP Alerts (alert, prompt, confirm) have been moved back to beta due to a few inherent instabilities in this feature. While we work on addressing these issues, the feature can be accessed using the feature flag enableAlerts in the manifest.json file. Also, note that UXP alerts will be available only in Plugins and not in scripts.

Adding the enableAlert flag in my manifest.json fixed it for me. Though it sound like this will be reverted at some point but it is not clear to me if I need to remove the manifest flag again.

True! It does work, it looks, though, like this is a different call (according to this) docs. Unfortunately, it doesn't seem that a showConfirm or any equivalent exists, so I still can't find an alternative for that

This works if run as a psjs file:

require('photoshop').core.showAlert(app.activeDocument.path);

I'm currently experiencing this same issue after updating to version 25.6.

As far as I understand UXP runs in the context of a browser VM, so running alert should implicitly call the window.alert function (notice is NOT window with a capital w), which I can imagine has a custom implementation in the context of the Photoshop application. I tested it both ways as window.alert and just plain alert and had the same result

Does this require the class name? In Extendscript the proper usage was always Window.alert() but you could use alert() and get away with it.

Well, I can confirm the last working version for these functions is 25.4. From 25.5 up to 25.6, they don't.

I tested it with this isolated project:
HTML:

<!DOCTYPE html>
<html>
<head>
    <script src="main.js"></script> 
    <link rel="stylesheet" href="style.css">   
</head>
<body>
  <sp-heading>Example</sp-heading>
  <sp-button id="button">example</sp-button>
</body>
</html>

JS:

const { entrypoints } = require("uxp");

  showAlert = () => {
    alert("This is an alert message");
  }

  entrypoints.setup({
    commands: {
      showAlert,
    },
    panels: {
      vanilla: {
        show(node ) {
        }
      }
    }
  });

document.getElementById("button").addEventListener("click", showAlert);
