Perhaps I could suggest xtemos to implement other code editor? Would be less work for support 😀 . For example, Divi theme uses I believe CodeMirror which shows these errors – https://i.imgur.com/qzZ3zGV.png
WoodMart works with either the WP Bakery builder or the Elementor builder at once, but not with both at the same time. The demo content would be based on the chosen builder. It is not possible to switch from one builder to another after setting everything up.
