When we try to link from one siteaccess to another we have a strange issues whereby the first level in the path includes the url_alias.
This is expected to be treated typically as a / or the name of the siteaccess, but we get the name of the url_alias.

This causes link cross site to not work as expected.

We have used the following twig function in our twig file:

url( 'ez_urlalias', {'locationId': locationId, 'siteaccess': 'myOtherSiteAccess'} )

Siteaccess default has treeNode set to for example = 10
Siteaccess myOtherSiteaccess has treeNode set to for example = 80

When we generate a link standing on the default siteaccess the new link includes the name of node80 in myOtherSiteAccess. This is not expected.
