Hey @segunadebayo !

Thanks for your feedback 🙏

I pushed a commit containing the changes asked. Let me know if i need to change something else. 😊

PS: with Abraham we noticed that attributes and handlers coming from the Svelte normalizer, are lightly typed compared to other frameworks. For example in react getRootProps will have the attributes returned by the normalize function(eg: "tabindex"), whereas in Svelte the attributes type will be Record<string, any>.
I am still looking for a way to improve this. Let me know if you want me to find a solution for this before moving on to the rest with Svelte. Thanks again 🙏
