Browser display connection fails: WebEngineContext used before QtWebEngine::initialize() or OpenGL context creation failed. QGLXContext: Failed to create dummy context

[GillesJ]

The opening of the browser window to verify or enter log-in information fails.

What changed: I upgraded all packages including openconnect-sso and deps through pipx and my browsers through apt.

The package still works by manually copy-pasting the url in my browser, but it was nice to have the window open automatically.
