Seen on magnolia-dx-core-webapp

Version number : 6.2 (Snapshot: 2020.03.26 11:30:03)
Core version : 6.2.0-SNAPSHOT
Build : 26. March 2020 (rev. c589ab5bb41a8c113a1d

Procedure to reproduce:

1. install DX Core empty webapp
2. login as superuser
3. open/close "Edit user profile" dialog
4. open About app >> FAIL

Seeing a reference to JiraLoginDialogPresenter, there appears to be a direct connection with MGNLUI-5549: Selected About-app@dx-core shows JIRA form when app is started

Magnolia cannot apparently handle the new superuser password change and the pre-filled credentials for the (obtrusive) Jira popup when the About app opens. Potentially this could be solved by MGNLUI-5549.
