The `wp_get_elements_class_name()` function previously generated CSS class names by hashing the serialized block data via `md5()`. Identical blocks received the same `wp-elements-*` class name and the Style Engine deduplicated their CSS rules into one, causing a parent block's element style (e.g. link color) to cascade down and override a child block's identical style due to CSS source order. The function is updated to use `wp_unique_prefixed_id()` instead, generating sequential unique class names (`wp-elements-1`, `wp-elements-2`, etc.) that match the block editor's JavaScript implementation. The now-unused `$parsed_block` parameter is removed from the function signature. PHPStan rule level 10 errors are also resolved in the related code. See #64898.
