Description

I noticed the RatingIcon component did not have any key property (this was also logged in console)

2:54:54 PM [vite] page reload /Users/leonardo/PersProgetti/qwik-ui/packages/headless/src/components/rating/rating.tsx QWIK ERROR JSXError: Multiple JSX sibling nodes with the same key. This is likely caused by missing a custom key in a for loop at eval (/src/rating_component_qsamuiuvsow.js:45:56) at Array.map (<anonymous>) at Rating_component_QSAMuIUvsOw (/src/rating_component_qsamuiuvsow.js:43:45) at async Promise.all (index 0) at async Promise.all (index 1) at async Promise.all (index 1) at async Promise.all (index 1) at async Promise.all (index 1) at async Promise.all (index 1) at async Promise.all (index 0)
