The unresizable dialog window

SUMMARY
The VPN secrets (openconnect) dialog window cannot be resized when trying to authenticate via HTTP user/pass. This is a big issue because the window is too small and cuts off the authentication webview to a small rectangle of the top-left corner of the page.

This issue makes it impossible to authenticate via a web page as you cannot see clipped content nor can you reposition the view enough to be able to view the entire contents of the page.


STEPS TO REPRODUCE
1. Open network manager
2. Create a new PAN Global Protect (openconnect) VPN connection.
3. Provide a gateway that will allow you to connect. I'm sorry but I don't know of an example gateway to provide that could be used for testing purposes.
4. You may need to sign into the KDE wallet, and then right click the new connection and click Connect.
5. Click the Connect button next to the VPN Host field
6. When the host is contacted and the webpage is rendered, try to resize the dialog window.
7. Observe that you cannot resize the window, and the webpage content is significantly cut off.

OBSERVED RESULT
You cannot resize the dialog window.

EXPECTED RESULT
You can resize the dialog window.
