@when definition isn't respected when using @alias in DocBlock

When using the @alias feature inside of a DocBlock, it doesn't seem to respect the @when definition when being called as the alias. Here is a test case where the command runs before_wp_load when using the standard name, but not when using the alias"

<?php

class Test_Command {
	/**
	 * test
	 *
	 * @alias bar
	 *
	 * @when before_wp_load
	 *
	 */
	public function foo( $args, $assoc_args ) {
		echo "Hello\n";
	}
}

WP_CLI::add_command( 'test', Test_Command::class );

When run in a directory that doesn't have a WordPress installation, the results are different:

$ wp test foo
Hello
$ wp test bar
Error: This does not seem to be a WordPress installation.
The used path is: /Users/mrsdizzie/
Pass --path=`path/to/wordpress` or run `wp core download`.

I checked and it does register the alias so that part is working:

$ wp help test foo
NAME

  wp test foo

DESCRIPTION

  test

SYNOPSIS

  wp test foo

ALIAS

  bar
