🔧 Bug Fixes & Patches (6)

Fixed #6391: the rule `noUselessFragments` no longer reports a fragment that contains whitespaces which aren't trimmed by the runtime.
Fixed #6360: The following pseudo classes and elements are no longer reported by `noUnknownPseudoClass` or `noUnknownPseudoElement` rules.
Fixed #6357, where the boolean values weren't correctly merged when using the `extends` functionality. Now Biome correctly merges the values.
Fixed #6341: Fixed an issue where Biome would throw an error for the language tags `nb` and `nn`.
Fixed #6377: The rule noSelfCompare now correctly compares two function calls with different arguments.
Fixed #6278: `useExhaustiveDependencies` no longer adds duplicated dependencies into the list.
