Indent level (parameters: first) for async arrow functions

Probably the same as #10531 which was automatically closed due to inactivity 2 years ago.

Tell us about your environment

ESLint Version: 7.4.0
Node Version: 14.5.0
yarn Version: 1.22.4
What parser (default, Babel-ESLint, etc.) are you using? espree & @typescript-eslint/parser

Configuration

const indentOptions = {
  "FunctionDeclaration": { "parameters": "first" },
  "FunctionExpression": { "parameters": "first" },
};
const indent = ["error", 2, indentOptions];

module.exports = {
  parserOptions: {
    ecmaVersion: 2018,
    sourceType: "module"
  },
  overrides: [
    {
      files: ["*.js"],
      parser: "espree",
      rules: {
        indent: indent
      }
    }
  ]
};

What did you do?

const foo = async (arg1,
                   arg2) =>
{
  return arg1 + arg2;
}

node_modules/.bin/eslint foo.js

What did you expect to happen?

Run without errors

What actually happened?

/private/tmp/foo/foo.js
  2:1  error  Expected indentation of 2 spaces but found 19  indent

✖ 1 problem (1 error, 0 warnings)
  1 error and 0 warnings potentially fixable with the `--fix` option.

Note: if I remove the async then the error goes away (the "parameters": "first" is honoured).
