Gnome-shell search always open new instance of gnome-terminal

If I search 'terminal' in shell and hit enter, it always open new instance of gnome-terminal.

How to regenerate:
1. Open a terminal (gnome-terminal)
2. Press super key or click Activities to start overview mode
3. Search for terminal and hit enter
4. It will open another instance of gnome-terminal

Expected behavior:
1. Bring already opened instance to front.
