Responsive layout looks incorrect when switching to landscape mode

Given a simple oh-page populated with standard oh-cells:

config:
  label: Home
  layoutType: responsive
blocks:
  - component: oh-block
    config: {}
    slots:
      default:
        - component: oh-grid-cells
          config:
            cols:
              "719": 2
              default: 5
          slots:
            default:
              - component: oh-cell
                config:
                  action: toggle
                  ...
              - component: oh-cell
                config:
                  action: toggle
                  ...

On my iPhone in portrait mode it works and looks as expected (cells are arranged by 2 cells per row)
When switching to landscape mode it shows 5 cells per row (as expected) but the width of the cell is wrong as can be seen here:

Can anybody confirm this or knows which config I need to change?

I don’t use any iDevices, so I can’t really help specifically. All I can say is that there have been numerous tweaks to the f7-card css with the new oh-card refactoring, and this, mostly likely, is a effect of one of those tweaks. As a result, it probably makes sense to file an issue in the UI repo.
