 * Hi there.
 * I’m trying to tweak the preview of a Gutenberg block to make it wider.
 * From the docs
 * > It’s also possible to define the width of the preview container in pixels via
   > viewportWidth
 * [https://developer.wordpress.org/block-editor/developers/block-api/block-registration/](https://developer.wordpress.org/block-editor/developers/block-api/block-registration/)
 * This is the code
 *     ```
       registerBlockType('my-plugin/dummy-block', {
       	...
       	attributes: {
       		...
       	},
       	example: {
       		attributes: {
       			...
       		},
       		viewportWidth: 1300,
       	},
       	...
       });
       ```
   
 * This is not working unfortunately.
    I’m running WordPress 5.6
 * Any ideas?

 * I had the same issue and found out it’s been released in Gutenberg 9.3 which 
   is included in WordPress **5.7** only. We updated to 5.7 and it works as described
   in the docs. If you are stuck with WordPress 5.6, I think you could install the
   gutenberg plugin to benefit from the newer versions ([https://wordpress.org/plugins/gutenberg/](https://wordpress.org/plugins/gutenberg/)).
 * (this PR introduces the feature: [https://github.com/WordPress/gutenberg/pull/26346](https://github.com/WordPress/gutenberg/pull/26346))
 * Cheers,
