💡 Description

• To avoid a synchronization problem where the suggestion was tapped and instead of being searched for, the overlay mode would get canceled, not performing the search based on the tapped suggestion, this PR checks for the toolbar refactor if the search term is nil, meaning that the search is not tapped nor highlighted, so it's okay to leave overlay mode.
