WebRTC: [Bug]: custom shortcuts and title overlap

The new custom shortcuts added in PR #169 create a layout issue. They overlap with the title, if it is configured.

type: custom:webrtc-camera
entity: camera.sd
title: Dining Room
ui: true
shortcuts:
  - name: Record
    icon: mdi:record-circle-outline
    service: switch.toggle
    service_data:
      entity_id: switch.camera_record
