messageFromChildHandler not triggered by dialog.url.sendMessageToParentFromDialog

[ignite-cykim]

When using the Microsoft Teams SDK v2 dialog.url.open() method and supplying a messageFromChildHandler as the third parameter, messages sent from the dialog via dialog.url.sendMessageToParentFromDialog() are not received by the handler.

To Reproduce

In the main app, open the dialog like this:

import { dialog } from "@microsoft/teams-js";

dialog.url.open({
  url: "https://mydomain.com ~ sthsth",
  size: { height: 400, width: 500 },
}, 
(result, reason) => {
  console.log("Dialog closed", result, reason);
}, // <-- This works
(message) => {
  console.log("Received message from child dialog", message); // <-- This never fires
});

In the dialog page:

import { dialog } from "@microsoft/teams-js";

await dialog.url.sendMessageToParentFromDialog({
  type: "MY_CUSTOM_MESSAGE",
  payload: "hello from child"
});

Observe that the messageFromChildHandler does not trigger.

Expected behavior

The third parameter (messageFromChildHandler) of dialog.url.open() should be called when dialog.url.sendMessageToParentFromDialog() is invoked from the child dialog.

Actual behavior

No message is received.

SDK version

@microsoft/teams-js: 2.13.0

Environment
