GrapheneOS has fixed the leak [by disabling a fast connection option](https://grapheneos.org/releases#2026050400:~:text=disable%20registerQuicConnectionClosePayload%20optimization%20to%20fix%20VPN%20leak). The AOSP team has marked this as ‘[won’t fix](https://issuetracker.google.com/issues/250529027)’. Perhaps iodé could also integrate this (possibly as an optional feature)? Or could the issue be passed on to LineageOS so that LineageOS can fix it for all LineageOS-based operating systems?

I notified our developers, not sure when they will get a chance to look into it.
