_Originally created by @intrigeri on [#12558 (Redmine)](https://public-redmine-archive.tails.boum.org/code/issues/12558)_ When connecting to a MUC, a dialog opens recommending OMEMO, OTR or PGP for MUCs. So this test scenario cannot pass. I assume that detecting and escaping this dialog should be trivial, hence the (close) target version, but feel free to postpone. Parent Task: tails/tails#10288
