Tabs and Posts Carousel | WordPress.org

Hello

The problem is displaying the Posts Carousel block as the content of the Tabs block.

Posts Carousel alone works OK: https://gitkoolitus.adplus.ee/2023/11/19/post-carousel/

If Posts Carousel is added as Tab content, long blank content will be displayed.

How this could be fixed?
