- Click any of the non-contact users in the search results
- Send a message
- Click the 3-dot menu right of the heading showing user s1
- Click add to contacts
- On the confirmation dialogue click Add
Expected behaviour: The "Contact request send" message should be displayed
Current behaviour: The "Contact request send" message is not displayed (it still has the "hidden" class).
