A problem at integration test:

File: tests/integration/features/chat/notifications.feature:293

  Scenario: Group-mention when group is not a member of the room                                # /drone/server/apps/spreed/tests/integration/features/chat/notifications.feature:293
    When user "participant1" creates room "room" (v4)                                           # FeatureContext::userCreatesRoom()
      | roomType | 2    |
      | roomName | room |
    And user "participant1" adds user "participant2" to room "room" with 200 (v4)               # FeatureContext::userAddAttendeeToRoom()
    Given user "participant2" joins room "room" with 200 (v4)                                   # FeatureContext::userJoinsRoom()
    When user "participant1" sends message 'Hi @"group/attendees1" bye' to room "room" with 201 # FeatureContext::userSendsMessageToRoom()
    Then user "participant2" has the following notifications                                    # FeatureContext::userNotifications()
      | app | object_type | object_id | subject |
      Notifications count does not match
      Failed asserting that actual size 1 matches expected size 0.
