I’ve noticed in the video on WordPress development (https://youtu.be/04VQfRaWJpc?t=181) that the custom attribute “blocs-wp-post-thumb” is being used. However I found no documentation at all about this custom attribute (or other potential custom attributes that apply to WordPress theming in Blocs) in the current documentation on WordPress.
Would it be possible to provide some documentation or a list of available custom attributes for WordPress theming?
Also, these custom attributes might open up possibilities to allow more things to be added to the customizer (https://codex.wordpress.org/Theme_Customization_API), for example:
blocs-wp-background-color to allow for a color selector in the customizer.
Thanks for such a great tool!
