Description Overview

shadowrootmode attribute of <template> is in Baseline 2024, so I expected eslint-plugin-react to recognize it.

Code:

package.json:

{
  "type": "module",
  "devDependencies": {
    "@eslint/js": "9.23.0",
    "eslint": "9.23.0",
    "eslint-plugin-react": "7.37.4",
    "react": "19.0.0"
  }
}

eslint.config.js:

import js from "@eslint/js";
import react from "eslint-plugin-react";
export default [
  js.configs.recommended,
  react.configs.flat.recommended,
  react.configs.flat['jsx-runtime'],
  {
    files: ['**/*.{js,jsx,mjs,cjs,ts,tsx}'],
    rules: {
      'react/no-unknown-property': 'error',
     },
  },
];

src/example.jsx:

export const Template = () => (
  <template shadowrootmode="open"></template>
);

results in

Unknown property 'shadowrootmode' found
(react/no-unknown-property)
[2:13-34]

Expected Behavior

shadowrootmode, shadowrootclonable, and shadowrootdelegatesfocus should be recognized (but probably not experimental shadowrootserializable).
