Grid Layout does not work as expected, for the following dashboard

views:
  - title: Home
    sections:
      - type: grid
        columns: 3
        cards:
          - type: button
            show_name: true
            show_icon: true
            tap_action:
              action: toggle
            name: Button A
            show_state: true
          - type: button
            show_name: true
            show_icon: true
            tap_action:
              action: toggle
            name: Button B
            show_state: true
          - type: button
            show_name: true
            show_icon: true
            tap_action:
              action: toggle
            name: Button C
          - type: button
            show_name: true
            show_icon: true
            tap_action:
              action: toggle
            name: Button D

I would expect it, according to documentation, to show three buttons before heading for the next row. This is however not the case as it is visualized like this
