Session data and instance media comes from clearnet domain when using tor/i2p mirror
That happens with external proxied media too but I have a workaround. That breaks being able to see media when not using the browser client but Husky added a fix. https://github.com/FWGS/Husky/commit/1432aa06f362c74a2400230c082eefe6c71d5b64
If I do the same with local media other instances won't be able to see my media.
