That's actually a theme-check bug I need to fix 🙈. @shopify/prettier-plugin-liquid is finally out of the door. I'll have time to do a round of bug fixes. I believe this has already been reported.

👋🏻 Hi @vfonic! Thanks for reporting this. Unfortunately the Ruby version of theme check has been deprecated for some time. Would you be able to confirm you are still having issues when using our maintained version of theme check? This is done using either the latest version of the Shopify CLI, or via the Shopify Liquid Visual Studio Code extension.

If you are still having issues, please raise an issue over in the CLI or theme tools repositories. Thanks!
