Lovelace UI in 81.x Limits Number of Horizontal Entities

In HA versions prior to 81.0, I have a Lovelace frame configured as follows:

    - type: glance
      column_width: calc(100% / 8)
      show_state: false
      #title: Lights
      entities:
        - entity: light.family_room
          name: FR1
          tap_action: toggle
        - entity: switch.wemo
          name: FR2
          tap_action: toggle
        - entity: light.living_room
          name: LR1
          tap_action: toggle
        - entity: switch.kasa1
          name: LR2
          tap_action: toggle
        - entity: switch.kasa2
          name: MBR
          tap_action: toggle
        - entity: light.porch
          name: Pch
          tap_action: toggle
        - entity: light.porch_2
          name: Pch2
          tap_action: toggle
        - entity: light.gateway_light       
          name: Alm
          tap_action: toggle

I made the names short so that I could display all 8 lights in a single horizontal frame. Since Upgrading to 81.0 (and all succeeding versions) the Lovelace UI displays only 5 of the lights on the first row, then 3 more lights on a second row. If you look at the Lovelace example cards, they are now also limited to 5 entities per row. Is this on purpose, or was there a bug introduced? Anyone else notice this behavior?
