Steps to Reproduce:
- Create a new page.
- Add the container fragment.
- Set the Content Display to Flex Row.
- Add two cards to the container.
- Publish the page.
- Both Cards should be rendered in one row, each taking up 50% of the width.
- Both cards take up the whole width and are rendered in one column.
It appears that the d-lg-block class is always being added to the container when published, which is taking precedence over the flex style.
