Use the Happy Eyeballs V3 algorithm for connection attempts

Controls whether Microsoft Edge uses the Happy Eyeballs V3 algorithm to optimize connection attempts. This algorithm improves reliability and performance in dual-stack (IPv4/IPv6) networks by racing connection attempts across IP versions and HTTP protocols (e.g., HTTP/3 vs. others). For more details, see https://datatracker.ietf.org/doc/draft-pauly-happy-happyeyeballs-v3. Enabled: Uses the algorithm for connection attempts. Disabled or not configured: Disables the algorithm. Note: This policy supports dynamic refresh. Important: This policy is temporary and will be removed in a future version.
