Broken CMS block preview when using identifier in pagebuilder

[rvr-robert]

Description (*)

When adding a CMS block in a CMS page using the block identifier instead of the block ID, pagebuilder displays following error : "Block with ID: [block identifier] doesn't exist." instead of showing preview of the CMS block.

The block renders properly on front-end.
There is no way to add a block with his identifier directly from pagebuilder. This issue would only happen if a developer executes a data patch that generates CMS content or directly edit the content in the database.

Hello @rvr-robert,

Thanks for the collaboration!

Please update the PR branch with the latest changes in the master branch. Then we will pick this PR for review. It seems the failures are due to this only.
