Thanks for reporting this, @maxming2333.

Great question about MJML Component tagUpdated will make it impossible to hover. The recommended approach with ProseMirror is to use the event-driven API.

Start here:

Check the GrapesJS documentation for your specific module
Look for the on() event listener method
Most operations can be achieved by listening to editor and component events

Common patterns:

// Listen for changes
editor.on('change', () => console.log('something changed'));

// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));
