NOT WORKING (longer content - only the number between 41 and 60 have been added)
The number of repeatable items does not seem to matter. Just the length of the meta stored within the html appears to make the difference. Once the content gets too long, it can still save but not anymore be switched into preview or edited when the page gets reloaded in the backend.
When it happens, in the console, the call to

Here is the block initialization:
