What's Changed

🐞 Fixes

• Fixed false negatives in the JSX element resolver used by the react-dom rules: polymorphic components written as member expressions (e.g. <motion.div as="button">) were mistaken for host elements, so the polymorphic prop was ignored and these rules skipped them entirely; they are now resolved through the polymorphic prop and checked like the underlying DOM element. String values of the polymorphic prop are also normalized to lowercase, so as="BUTTON" is treated as button. Affected rules:
  • react-dom/no-missing-button-type
  • react-dom/no-missing-iframe-sandbox
  • react-dom/no-unsafe-iframe-sandbox
  • react-dom/no-unsafe-target-blank
  • react-dom/no-void-elements-with-children

🏗️ Internal

• The normalized polymorphicPropName setting type is corrected from string | null to string — it could never be null at runtime — and the unreachable null branch in the JSX element resolver used by the react-dom rules is removed.
