[BUG] `textable` component disappears with custom RTE

1. Are you using the latest release (older versions are NOT supported)? Yes

2. Are you facing the bug with your local copy of GrapesJS or with the current demo? Current demo & local, also using the CKEditor plugin

3. What is the expected behavior? When a textable component, e.g. #481 Merge field is dragged into a text area (i.e. paragraph, heading), it renders accordingly (as it would without the custom RTE)

4. What happens instead? The component disappears

5. If you're able to reproduce the bug indicate all the necessary steps

• Add the grapesjs-ckeditor-plugin
• Add a textable component to the canvas
• Drag into an area that the RTE has usage in

Attach screenshots (using KAP/LICEcap), screencasts or live demo Here is the working component with the default RTE showing the functionality of the textable component:

Now here it is (disappearing) with the grapesjs-ckeditor-plugin:
