Microsoft Teams Trello login redirects to browser

When attempting to login in to a Trello board in MS Teams, I am being redirected to a browser login instead of the normal popup login window I would expect to see.

Default browser is Edge. Pop-ups for "atlassian.com" are allowed. Pop-ups for "trello.com" are allowed.

Anyone have suggestions?

Discovered a work-around minutes after posting this.  I "popped out" the MS Teams tab (Trello board tab), clicked login, and got the expected "pop up" to do a web login.
