Office-js: Outlook: Office.context.mailbox.item.displayReplyAllForm doesn't start callback

[NT-D]

Office.context.mailbox.item.displayReplyAllForm doesn't start callback. We don't update our code, but this function doesn't start call back after we update Outlook through Microsoft Update (not sure but probably it may affect).

Expected Behavior

Office.context.mailbox.item.displayReplyAllForm invoke callback function as written in document.

Current Behavior

Office.context.mailbox.item.displayReplyAllForm create reply all form and inject html body expectedly, but it doesn't invoke callback.
I investigated through displaying error. I can see 'Start' but can't see 'CallBack' in browser debugger view with following code.

console.log('Start')
Office.context.mailbox.item.displayReplyAllForm({
                htmlBody: 'Insert html body'
                // eslint-disable-next-line @typescript-eslint/no-explicit-any
                callback: (asyncResult: Office.AsyncResult<any>) => {
                    console.log('Callback')
                }
            })

Steps to Reproduce, or Live Example

1. Create sample app using Office.context.mailbox.item.displayReplyAllForm. You may call this method from button.
2. Launch app on Outlook for Mac.
3. Call this method by clicking button. => Call back is not invoked.

In 1 ~ 2 weeks ago, my colleague repro this issue, but I didn't have issue in my environment even if we have same OS version and Outlook version. But I can repro today, so I'm not sure about correct repro step and root cause.

If you want to see the problem, I can make time to have Teams call (screen sharing) with product team or I can send captured video if product team share me email address.

Context

We want to communicate with server side after user see reply email form. If this callback is not invoked, we can't post necessary data to server side, as a result following process stops.

Your Environment

• Platform [PC desktop, Mac, iOS, Office Online]: Mac (Catalina 10.15.3 (19D76))
• Host [Excel, Word, PowerPoint, etc.]: Outlook for Mac Version 16.34 (20020900) with Office 365 Subscription
• Office version number: Version 16.34 (20020900)
• Operating System: Mac OS X Catalina 10.15.3 (19D76)
• Browser (if using Office Online): I've not tested in Office Online.

Useful logs

No log and screen shot, because callback is not invoked and can't write log.
