Routes within a domain group do not work correctly

Missing Protocol

When using routes in a domain group, the domain is added by the js route() function, but there is no protocol attached, so the url returned is incorrect.

in web.php

Route::domain('example.org')->group(function() {
	Route::get('/help', function () { 
			return 'help'; 
		})
		->name('help');
});

in blade/js

route('help'); 
// returns 'example.org/help' 
//     instead of '//example.org/help' 
//             or 'http://example.org/help'

Missing Port

Another thing is that if Laravel is running under example.org:81 the php route() function adds the :81 to the url, if its the current domain.

If the current URL is ‘http://example.org:81/home’

dump(route('help'));
// returns 'http://example.org:81/help'

but in JS

route('help'); 
// returns 'example.org/help' 
//     instead of '//example.org:81/help' 
//             or 'http://example.org:81/help'
