Describe the issue you are experiencing

When casting a dashboard to Chromecast, there are blank spaces visible on the casted display where visibility is being used to hide certain cards. These blank spaces are only shown on the casted display - they are not visible when viewing the same dashboard via a laptop web browser.

Describe the behavior you expected

Hidden cards should not leave blank spaces on a casted dashboard.

Steps to reproduce the issue

1. Create a dashboard with a hidden card as the first element using visibility
2. Add other cards below the hidden card
3. Cash the dashboard and observe the blank space displayed on the casted dashboard where the hidden card is located
4. Compare this to what is displayed (no blank space) when viewing the same dashboard via web browser
