// ## Issue
// This test reproduces an issue with the publisher.
// When switching local focus, we need to recreate the publisher.
// This failed because of a dead lock in the old publishers destruction.
//
// There are numerus ways to enforece this situation:
// - oldest member swap (manually set the oldest member focus and leave with the prev oldest member)
// This almost never happens in the real worls since clients will set their preferredFoci list to what the oldest member is.
// - switch from oldest member to multi sfu as the NOT the first joiner + the first joiner is on a different sfu than your preferred sfu.
//
// This test uses the "switch from oldest member to multi sfu" approach.
//
// It is a copy of federated-call.test.ts in the `["legacy", "legacy"]` setup,
// which once connected will make the second user switch to multi sfu.
