Compatibility info appears to be missing, eslint 9 config, 6.0

Is this plugin actually broken?

`eslint.config.js`
```js
...
{
files: ['dist/*.js'],
...compat.configs['flat/recommended'],
languageOptions: {
ecmaVersion: 2018,
globals: {
...globals.browser,
}
},
settings: {
browsers: 'last 10 years'
}
},
...
```

Run against https://github.com/replete/biscuitman/blob/main/dist/biscuitman.js
yields:
```
/biscuitman/dist/biscuitman.js
278:16 error Intl is not supported in Safari 7.1, iOS Safari 8 compat/compat

✖ 1 problems (1 errors, 0 warnings)
```

There are so many incompatible things not being picked up here that something must be wrong.

I've just set 10 years to test if this was working at all, because no errors were coming through. Is this a recent issue or has this been broken for a long time?
