Hybrid blocks, multi-language?

We do not necessarily have all the plugins (and in this case, not those that absolutely require a commercial license to be tested) but we do make sure to follow the development guidelines of WordPress, which in most cases, provides excellent compatibility.

It is not excluded that special cases may occur, sometimes due to bugs, sometimes due to specifics that escape us, and we examine each feedback on a case by case basis as long as we get enough details about the issues.

Note: from what I see here: Fixing WordPress block translations - #5 by madjedo
some modifications are in the pipeline for a future update.
