• 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": ["error", { argsIgnorePattern: "^_" }],
  }
}

// your repro code case

export interface Bar<_A> {
  readonly foo: string;
}

Expected Result

I expected the _A parameter not being used to be ignored becuase it is prefixed with an underscore and therefore part of argsIgnorePattern.

Actual Result

error @typescript-eslint/no-unused-vars : '_A' is defined but never used.
