// A failed user action is said once, and a user who is gone is not left listed (deep-review round 4).
// setRole / suspend / delete had no onError at all — "the global error dialog says it" — but a 404
// (the user was deleted in another tab) gets no dialog, so the click did nothing and the row stayed.
// And the invite approve/deny toasted unconditionally on top of the dialog `req` opens for a 409.
