Bug 463432

SUMMARY
Hi,

From either KAddressbook, KOrganizer, Akonadiconsole, if I try to setup a Card/Cal DAV account, I can go up to the step where an URL is provided to inspect the available connection. My DAV server is a Nextcloud instance running in a private network and use a self-signed TLS certificate, a dialog box to warn me and require approval is expected, but :

1. The dialogbox is hidden bellow every other window and cannot be elevated (I have to minimize every other window)
2. I cannot interact with this dialog bog: mouse clicks are not registered, neither are keyboard attempts

The dialog cannot be closed until other wizard window are also closed, and I cannot configure anything. I tried to add the self signed cert to the global CA database, it shows in the KDE SSL preference windows but the dialogbox still "appears"

If I try http, I will get another dialog box with a different warning (telling me password is plain on the network) but same behavior. 

Thanks for your time and KDE.

STEPS TO REPRODUCE
1. New KDE/Neon install, install Kontact
2. Open Kontact, add new adressbook
3. Fill credentials, click to fetch collections, select Card/Cal DAV, fill URL

OBSERVED RESULT
Cannot click on the ssl warning dialog box.

EXPECTED RESULT
Dialogbox is expected and message correct, but I would expect to be able to be able to click on its button to proceed futher
