Hi @inkedraskal
Big thanks for your waiting!
I was considering various options to fix the problem you wrote about. I tried to find the most non-invasive solution that would fix the problem but not create new ones (this always happens when developing a plugin that is used by tens of thousands of users with different versions of WP, PHP, and MySQL).
But finally settled on a solution that I ask you to test on your site. In a private message, I sent a link to the new version of the Pro plugin.
Please install it and let me know if it fixes the problem.
Note that this problem is not directly related to your theme; it is much deeper and concerns the fact that Wordpress deliberately removes all HTML tags when rendering the core/post-excerpt block, and thus, this problem will be present in ANY block theme.
The new version fixes this. I managed to get this effect without editing WP Core, only with the help of hooks.
Thank you very much. Your request made the product better. And the whole WordPress world, because this solution will be implemented in a free version also.
