IP packet capture on loopback adapter with wireshark 4.x + NpCap

edit

Environment: - Windows 10 - Wireshark version: 4.4.x - Npcap version: 1.8 - Using virtual loopback

Problem: - IPv6 TCP SYN packets sent on loopback address from LAN adapter (::1 / fd29...). - IP address on loopback responds TCP SYN with TCP SYN ACK.
- Wireshark with "Adapter for loopback traffic capture" shows no packets

Observations: - Wireshark claim that with NpCap the ipv6 packets can be captured on loopback interfaces

Expected: - Wireshark/Npcap should capture IPv6 loopback TCP SYN packets

Actual: - No packets seen on loopback adapter

Question: - Is IPv6 loopback capture supported via Npcap? If yes, then am i missing some windows setting. - Any workaround to capture TCP SYN IPv6 on loopback on Windows?
