• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.
• I have read the FAQ and my problem is not listed.

Repro

{
  "rules": {
    "@typescript-eslint/no-unused-vars": [
      "warn",
      { "argsIgnorePattern": "^_", "ignoreRestSiblings": true }
    ]
  }
}

export type F<A extends unknown[]> = (...a: A) => unknown;

Expected Result

No error

Actual Result

Error - 'A' is defined but never used.eslint@typescript-eslint/no-unused-vars

Additional Info

When removing the ... before a, the error is no longer reported (although obviously this is a completely different type - just including this info in case it's helpful). i.e. this is fine:

export type F<A extends unknown[]> = (a: A) => unknown;
