Describe how other contributors can replicate this bug

Register commands

add_action(
	'cli_init',
	function () {
		WP_CLI::add_command(
			'first',
			function () {
				WP_CLI::runcommand( 'second' );
			}
		);

		WP_CLI::add_command(
			'second',
			function () {
				WP_CLI::log( 'second' );
			}
		);
	}
);

setup alias in ~/.wp-cli/config.yml

@wp:
  path: [PATH_TO_PROJECT]

and run wp @wp first not from current project directory.

Describe what you expect as the correct outcome

Expect second output but has warning No WordPress installation found

Provide a possible solution

Should add current alias to $runcommand string.
