Closing a Tab Configuration Dialog Orphans Authentication Pop-up Window
Our team has encountered a bug with MS Teams handling of an authentication popup window when launched through a Tab Configuration dialog.
1) Go to a Team channel and click the + button to add a new tab.
2) Select an app that requires authentication as part of the tab configuration process.
3) Initiate the authentication process. The authentication pop-up window should appear.
4) Before the authentication pop-up completes, close the Tab configuration dialog.
Expected results: The authentication pop-up window should be closed/cancelled when the tab configuration dialog is closed, or closed when the notifySuccess/notifyFailure events are triggered.
Actual results: The authentication pop-up continues running, and doesn't close on completion (likely because Teams is no longer listening for the notifySuccess/notifyFailure events).
