@fabiankaegy, how do I test this? I tried building and copying over the dist files to the project node_modules folder, but then the project is not being built. I tried replacing the whole package, also issues with building

🎉 A new testing version of this package has been published to NPM. You can install it with npm install @10up/block-components@testing-253

@av3nger In order to make it easier to test I released a testing version to NPM. See #253 (comment)
