System Alias on an external System URL doesn't work

[uglyeoin]

Steps to reproduce the issue

I create a menu item with a URL and it's an external URL.
Then I create an alias to that menu item.
When clicking the alias, instead of opening the URL, opens a Joomla link which is a 404. e.g. https://domain.co.uk/?Itemid=218

Expected result

Clicking the alias goes to the URL

Actual result

Clicking the alias goes to a Joomla item

System information (as much as possible)

Another user also reported.

I think it is a bug in the router. I have the same problem when I try to resolve a menu item of type URL using the menuitem field on an own module
