Content Display Block – Masonry bug

Hi.

The plugin has been great for me. I have encountered a problem using the Content Display Block. When the page alters its dimension during loading, the Content Display Block with Masonry option often creates a space underneath, or in other cases the blocks are definitely out of alignment. In the web page where I report the problem I have put a clean WordPress installation with some themes, and I have left a video so that you can appreciate the problem. In the final part of the video you can see the problem on a page in production.

Thank you for your attention.
