Content is hidden before header.

@alok_singh thanks for creating patch, patch applied successfully.
Here are the steps I took to reproduce the issue
1. Installed "YG Business | Bootstrap based Drupal 9 theme for Business" Theme using composer.
2. Add test node or content type.
3. Refresh the page and go back to the homepage.

Result:- Now content is showing properly.
But there are showing some issues like site branding logo image missing, menus missing in the header section.
I am sharing screenshots for reference.
Thank you.
