ConfirmDialog: closing animation is replaced by secondary dialog animation

[icenitipol]

Describe the bug

Bug description

ConfirmDialog closing animation works normally when only one dialog is used.

However, after opening a secondary ConfirmDialog from inside the footer of the main ConfirmDialog, the main dialog closing animation appears to be replaced by the secondary dialog's closing animation.

When the main dialog is closed later, the secondary dialog briefly flashes as a ghost / duplicate popup during the closing animation.

This only happens after the secondary dialog has been opened at least once.

Steps to reproduce

Case 1: Works correctly

1. Click "Open Main Dialog"
2. Close the main dialog using the X button, or click "Accept - valid"

Expected:
The main dialog closes with its own normal closing animation.

Actual:
The main dialog closes correctly.

Case 2: Animation bug

1. Click "Open Main Dialog"
2. Click "Accept - validation error"
3. A secondary dialog opens
4. Close the secondary dialog using the X button, or click OK
5. Close the main dialog using the X button, or click "Accept - valid"

Expected:
The main dialog should close using its own normal closing animation.

Actual:
The main dialog closing animation appears to be replaced by the secondary dialog's closing animation.
A ghost / duplicate of the secondary dialog briefly flashes while the main dialog is closing.

Important note

The issue does not happen if the main dialog is opened and closed directly.

The issue only happens after the secondary ConfirmDialog has been opened at least once.
