BUG: System Proxy not working on KDE 6

[amirsina-mashayekh]

Describe the problem

Expected behavior:
When activating "System Proxy", proxy in KDE settings should be set to nekoray proxies.

Actual behavior:
Activating and deactivating System Proxy has no effect on KDE Proxy settings. Tun mode and manually setting proxy to 127.0.0.1:2080 work fine.

How to reproduce

• Install KDE 6 (In my case, Plasma 6.3.2 [KF 6.11.0] [Qt 6.8.2] (x11) on openSUSE Tumbleweed)
• Download nekoray-4.0.1-2024-12-12-linux64.zip, extract and run it
• Add some configs and connect to them
• Activate "System Proxy"
• Check System Settings > Networking > Wi-Fi & Internet > Proxy
• It is still on "No proxy", should be on "Use manually..." as I saw in KDE5
